The sunda-mud made glass is prepared, according to "Paarthiva-paaka Kalpa" as follows. Take salt, shinjeera, bone, and betel-nut salt, durona, kuruvinda grass (cyperus rotundus), gum, sowraashtra mud, virinchi vatika or banyan bark, silk cotton tree bark, and coir salt, these ingredients are to be taken in the proportion of 5, 12, 2, 3, 8, 3, 30, and 6, purified, filled in the crucible, and placed in the tortoise shaped furnace, boiled 32 times in 100 degree heat with the help of two faced bellows, and the resulting fluid poured into the cooling yantra. A pure and fine sunda-mud-glass will be formed.
With the glass thus produced by boiling 32 times, a base is to be formed 12 inches wide, 3 inches high, four-square or circular. From the centre of it 4 kendras or centres are to be marked. In the centre an arm-sized pivot made of the said glass should be fixed. On top of it is to be fixed the cold-processing mirror key. At its centre should be fixed the cold producing crystal. At the eastern centre should be placed the acid vessel.
Dravapaatra or acid vessel is described in "Kriyaasaara." It should be 12 inches wide and 12 inches high, shaped like a tumbler, circular, and hard like a cocoanut shell, and be made of the sheeta-ranjikaa glass.
The glass is described in "Darpana Prakarana". Shasha-piththa, udupiththa, borax, kutmala, jyotsnaa saara, rasonta kanda flour, kudupa-salt, mica salt, shoundeera jangha shalya flour, vaatohara, white niryaasa earth salt, and uragha.
These 12 ingredients should be taken in the proportion of 5, 3, 5, 1, 10, 10, 11, 8, 7, 2, 20, and 6, and after properly purifying them, fill them in lotus-shaped crucible, and placing it in the lotus shaped furnace filled with p. 52 burning charcoal, and with the aid of the five-mouthed bellows blow the heat to 323 degrees temperature, and pour the liquid into the yantra. The resulting glass is called sheeta-ranjikaadarsa or cold-receptacle glass.
Cold-producing crystal is described in "Maniprakarana": 5 parts of couries and manjula powder, 4 parts udumbara salt, 3 of rubhna, 8 parts of varchulaka, 7 of sheeta ranjikaadarsha, 3 of vatu, 28 of shaalmali, 3 of salts, 7 of mercury, 8 of white mica, 8 of karkataanghri salt, 5 of chowlika satva, 15 of niryaasa earth, 25 of sampaathi bird kneebone-These 14 ingredients, in the named proportions are to be purified and filled in mritkundala-moosha or earthen crucible, and placed in kulakundika furnace, and with the aid of tryambaka bellows blown into 300 degree temperature. Fill the boiled liquid into the mani-prasoothika, or crystal forming yantra. The crystal produced will be pure, hard, and intensely cold.
In front of it should be fixed.the electric panka wheel, with 100 spokes and electric wiring, and purified by 3 acids.
As per "Kriyaasaara," 12 parts of copper, 3 of collyrium, 8 of zinc, should be mixed and melted with 100 degree heat. It will become pure like gold, yellow, fine, soft, and strong. It is called pancha-loha or five-in-one metal by those who know. 100 leaves like those of lotus should be formed out of them. Then 3 navels, three navel keys, and 3 wires, and a sounding keelaka or key, or switch, or wheel.
First the navel wheels with hinged rods should be fixed so that the 100 petals will he made to revolve with due speed on the four sides of the wheel. Similarly by the side of the wheel in front of it, another 100 petals should be properly fixed for revolving in reverse direction. And electric wires should be fixed on both sides of the centre of the western wheel, for operating the 100 spoked electric panka or fan. Then the vessel should be filled with the cold generating acid. And encircling the cold-generating mani or crystal, it should be placed in another vessel in the centre. And copper wiring enclosed in milk-cloth should be attached to the wire in the acid vessel. Two wires from there with switches should be connected with the cold ranjikaa glass or mirror in right-turning fashion. Then current should be switched into the electric wiring in the crystal and acid. Then by the contact of the electric current the forces within the crystal and the acid will get active and their p. 53 combined cooling and comforting quality will enter the cold ranjanikaa mirror and concentrate in it.
On operating the switch attached to it, the cold effect will spread out all over the interior of the vimaana, and overcoming the scorching seasonal effect, make it comfortable and pleasant for the pilot, and restore his efficiency. Similarly the 100 spoked panka (fan?) should be switched on, when a breeze will be generated and air-condition the atmosphere of the pilots. Thus by the use of the crystal, acid, and panka, a state of pleasant comfort will be induced, and vigour, exhilaration, and competence will be injected into all the limbs of the body. Therefore this Pushpinee yantra should be installed in the southern section of the vimaana.
Next Pinjula Aadarsha or Pinjulaa Mirror:
By the collision of two winds giving rise to a whirlwind, and the fierce solar ray dashing against it, a lightning bolt erupts and strikes the unwary vimaana. To protect against such an event, the pinjula mirror is to be installed. An eight petalled lotus is to be made of the pinjula glass. Where the petals join, a circular dandaakaara should be made. At the back two hinged bolts should be fixed. They should be wound round by wires from the cold mirror. The back should be covered with a coirmade cloth covering. It should be fixed in the southern side of the vimaana, at an arm's height, facing the sun. The lightning will be absorbed by the projecting rods coiled with wires from the cold aadarsha mirror, and no evil effect will occur, and the pilot can proceed in safety.
And Naalapanchaka or Five tubes:
If the smoke from the kitchen over of the vimaana spreads, it will cause discomfort for people inside. Therefore the five tubes or pipes should be inserted for the smoke to go out and the air become clear. The pipes are to be manufactured as follows. Magnetic iron, pinjula mica, ghontaara metal, dhoomapaasya metal, and tortoise shell, are to be taken in the proportion of 1, 7, 5, 5, 8, purified, filled in crucible, and melted with 100 degree heat, and when ultimately cooled, a fine metal called vaataayanee metal, or window metal will result shining like gold.
With that metal 5 tubular outlets, 12 inches in diameter and 12 inches in length, should be fashioned. At one end of each of the tubes should be fixed p. 54 a smoke-absorbing crystal. The tubes should be inserted in the 4 sides of the vimaana, forming outlets. One tube should be fixed at the ceiling. The dhoomapa crystals will attract the smoke and pass it to the outside, and clear the vimaana of its discomfort. Hence the necessity for the naalapanchaka, or five tubes.
Then Guhaa-garbha aadarsha yantra, or hidden mine discovering mechanism:
According to "Yantra Sarvasva" enemies would have placed mines and bombs underground for the destruction of the vimaana, unless they are discovered and de-fused in time there would be danger. Therefore the mine-finder yantra has to be installed in the vimaana.
Says kriyaasaara, out of the 72nd type of glass, make a triangular, a circular, and a quadrangular shaped glass mirrors. These are to be fixed as follows with bolts made of pancha-dhaaraa metal in a frame made of the wood of the anjishtha tree. The circular mirror should be fixed at the bottom facing downwards. The quadrangular mirror should be fixed facing upwards. The triangular mirror should be fixed to the west of these two, with a panchamukha keelee or 5 faced hinge.
From the main pivot of the quadrangular mirror to the foot of the bolt at the south-east corner of the yantra, wires made of copper, tiles, and panchaasya metal should be drawn and connect them, and then the wire ends and chumbaka crystal should be placed in the mercuric-sulphur acid vessel. Four other wires should be made to circle the triangular mirror, pass through the mirror facing upwards, and fixed to the centre of the down-ward facing mirror. Then solar rays should be let in from the western side. A screen cloth coated with mirror-like gum should be placed opposite to the triangular mirror. Then the solar rays and electric current should be passed into the acid vessel containing the crystal. When the electrified rays from the crystal are passed on to the downward facing mirror, they will explore the ground over which the vimaana is to pass, and discover mines and bombs like mahagola and agni-garbha, which may have been inserted there and reflect their complete picture in the crystal in the acid vessel. The picture will then be projected to the screen opposite in clear detail, and by washing with chemicals present a perfect photograph of the buried mines and bombs, which could then be destroyed by due safety measures. Therefore the guhaa-garbha aadarsha yantra or mine-discovering yantra is essential for a vimaana.
First the 72nd type of mirror, known as suranjitaadarsha. "Darpana Prakarana" says:
Madder-root, live coal, ox-gall, snake-gourd, mercury, karanja or galedupia arborea, copper, 3 kinds of sharkara (sugar or sand?), borax, sulphur, chaaru or silk-cotton bark, lac, kuranga, rouhinee, iron-rust, panchaanana, liquid amber, Shiva or brionia laciniosa, vishwa, mica, paarvanija, vydoorya gem stone, in the proportion of 11, 27, 5, 7, 7, 3, 7, 5, 20, 3, 7, 3, 1, 32, 30, 38, 8, 7, 3, 9, 30, duly pulverised and filling in a beaked crucible, placed in a vaaraaha furnace, and heated to the 100th degree with the aid of the tortoise-shaped bellows. When the finely boiled liquid is poured in the cooling yantra, suranjika glass of exquisite quality will result, out of which three mirrors have to be fashioned for the guhaa-garbha-aadarsha yantra.
Kriyaasaara says, "Many kinds of trees are suitable for use in making yantras. Of them all the tree called aanjishtha is the finest." "The trees having 5 qualities are 87 in number. The best among them all is aanjishtha," says "Udbhijya tatva saaraayanee."
Agatatvalaharee also says, the five qualities such as the capacity to capture reflections, and others, are found inherent in the Aanjishtha (or madder root) tree. Therefore out of all woods the wood of that tree is most suitable for use in this yantra.
In making yantras, pivots of various metals are being used. But for use in connection with the guhaa-garbha-aadarsha, or hidden mine discovering instrument, the shankus or pivots made of pancha-dhaaraa-loha or five alloy metal are the best.
Kshvinkaa, iron-pyrites, copper, indra, and ruruka, purified, powdered, and filled in mrugendra moosha crucible and boiled to 300 degree heat with beaked bellows, will yield a 5 alloy metal, strong and heavy.
p. 56 Paara-granthika acid for insertion of the crystal, is described in "Moolikaarka prakaashikaa."
Mercury, bamboo salt, Indian spikenard joint, paarvanika or clerodendrum phlomides, svarna seeds or Indian labernum seeds? or yellow thistle seeds?, and ghatotkaja or American aloe, in equal quantities, should be filled in a big bellied earthen pot, heated to yield a golden hued shining liquid, which is very useful for capturing reflections.
Chumbaka crystal is the one most suited for use in capturing reflections of objects. It is manufactured as per "Manipradeepikaa," with the following ingredients. Magnet, sand, borax, ivory, shoundika or long pepper, mercury, paarvana or clerodend rum phlomoides, copper, vermillion, iron-pyrites, grudhnika, souri or marking nut, buffalo hoop, vishwakapaala, cleaned and powdered, and filled in karpala crucible and baked in a furnace with the aid of owl-nosed bellows to 100 degrees, will yield a fine image producing crystal.
Pigment for coating the screen so as to present a clear picture, is called "Roopaakarshananiryaasa," or image reproducing niryaasa or varnish. Out of 360 such varnishes that is the best.
Says "Niryaasa kalpa":
Moonstone, crownchaka, bamboo rice, five milks from banyan, fig, keg etc., trees, magnet, udusaara, mercury, mica, pearl, earth from ant-hill, saarasvata oil, and nakha or nail? these 16 articles to be taken in equal parts, purified, should be ground for a period of 30 days in the juice of the peacock's egg, then mixed with bilva oil and boiled for four yaamaas or twelve hours until it becomes a perfect gum or varnish. Some call it reflector varnish. Some call it virinchi-varnish.
The varnish is to be evenly spread on the special cloth called patadarpana, so that it may present as on a cinematograph screen, the pictures reflecting the location of anti-aircraft mines discovered by the roopaakarshana yantra.
The production of Pata-darpana is described in "Darpana-prakarana":
Gum, cotton, pratolikaa, kuranga or pallatory root, maatanga or keg tree bark, cowries, kshoneeraka, gholikachaapa, granite sand, parotikaa, sea-foam, priyangava, ghanjhotikaa, sugarcane, rukma or argemone mexicana, p. 57 kesara or mesua ferraa gum, earthen salt, suvarchala, urugha, bydaara oil, muchukunda flour, sinjaanu, anchaalika, turmeric, kaarmuka or acacia catechu, these ingredients in the proportion of 100, 58, 25, 28, 4, 12, 5, 3, 1, 30, 10, 5, 8, 12, 3, 13, 22, 27, 28, 3, 24, 7, 3, 13, should be cleansed, powdered, filled in a vessel, and boiled in the furnace with 100 degree heat, and the unified fluid should be poured on a flat surface so as to form an even surfaced sheet. After drying, the photographic niryaasa varnish is to be used to coat this sheet, for use in the Guhaa-garbha aadarsha-yantra.
Thamo yantra or Darkness creating yantra:
Vimaanaas are liable to be attacked by enemies with poison fumes of Rouhinee or krakachaarimani rays. As a protection against it the thamo yantra has to be installed in the vimaana. Out of 132 types of thamo-yantras, the 62nd variety is said to be the best for safeguarding against poison fume and ray attacks by the enemy.
Black lead, aanjanika (collyrium?), vajra-tunda are to be powdered and mixed in equal quantities, filled in fish-shaped crucible and placed in crow shaped furnace, heated to 100 degrees, and poured into the cooling receptacle will yield a fine, light, strong thamo-garbha-loha, or darkness impregnated alloy metal, useful for making Thamo-yantra.
