The peetha or stand is to be 3 feet wide and ½ foot high, square or round. In the centre of it is to be fixed the pivot. At its front should be placed the vessel of the acid of guggala or Indian dellium.
To the west should be fixed the mirror for enhancing darkness, and in the east should be fixed the solar ray attracting tube. In the centre should be fixed the wire operating wheel, and to its south should be fixed the main operating wheel or switch.
Its working is as follows. On turning the wheel in the south east, the two faced mirror fixed to the tube will revolve and collect the solar rays. By operating the wheel in the north west, the acid in the vessel will begin functioning. By slightly moving the wheel in the south-east, the solar rays will enter the crystal in the acid vessel. By turning the wheel in the west, the darkness intensifying mirror will begin to function. By turning the central wheel the rays attracted by the mirror will reach the crystal and p. 58 envelop it. Then the main wheel should be revolved with great speed, when the darkness will be produced enveloping the vimaana and making it invisible, and the efforts of the enemies to attack it with poison gas and rays will miss their target and become ineffective. This yantra should be placed in the north-west sector of the Vimaana Panchavaataskandha-Naala.
Iron rust, shaarana, copper, suvarchala salt, in equal parts, to be filled in mayookha crucible, placed in jumboo-mukha furnace, and using kaakamukha bellows boiled to 102 degrees and cast in the yantra, will yield a pure, light, soft, strong, nice cool metal known as vaatadhaarana loha.
4 tubes, each 2 yards long and 1 yard high, should be prepared. Like the circular opening in the top of the vimaana two openings on each and one at the bottom should be prepared. Each tube should be inserted in the said openings. Another tube 12 feet long and 3 feet high should be fixed on the western side in the opening at the top. To each tube should be attached bellows' mouth operated by wheels. By turning the wheels of the 5 tubes the 5 poisonous winds will be sucked in and passed into the tubes to make their exit, without causing harm to the plane.
There are 13 air layers known as Vrishni and others. By the force of the Panktiraadhasa Kendra, they tend to jostle each other, and generate fierce forces which will be destructive to the unwary vimaana which may get involved in them. Therefore the Pancha-Vaata-Skandha-Naala Yantra is to be inserted in the back portion of the vimaana; to safeguard against evil consequences.
Roudree Darpana Mirror.
From the south-eastern side of the earth-sun axis solar rays touch the turbulent forces in the etherial regions, and burst into flames, and vimaanas which may be out on their course may be destroyed by the flames. To prevent such a happening the roudree-darpana yantra should be installed in the bottom of the vimaana.
Says "Yantrasarvasva", "At the time when spring passes into summer, the forces in the junctional regions of the sky, on contact by fierce solar p. 59 rays, burst into tumultuous flames, and destroy all things that pass through, Therefore the roudree darpana should be fitted in the vimaana as a safe-guard against that."
According to "Darpana Prakarana," iron rust, magnet, veera iron, borax, panchaanana metal, mica, honey, red castor bark, banyan, suryavarchula or sweet-salt, gold, alika, shaarkara or benzoin tree bark, pancha tikta or 5 sours, snake gourd, and paaduka, are to be powdered, cleaned, and in equal quantities filled in padmaasya crucible, and placed in vishvodara furnace and heated to 200 degrees. The molten liquid poured into the mould will yield excellent flame-proof roudreedarpana glass.
With this roudree-darpana glass a plank of 16 feet in dimension should be prepared. A pivot 25 inches thick should be fixed at the centre of the plank. At the edge Of the pivot, two wheels should be fixed revolving with right motion and reverse motion for expanding and contracting. A wheel equipped with rods for spokes should be fixed, the spokes being 15 inches from each other.
Sheets made of roudree glass, washed with linseed, drona or lucas aspera, liquid amber, and madder root oils should be fixed to the rods with hinges. Similarly crystals made of roudreedarpana glass, with 5 facets, cleaned with the oils should be fixed at the end of the rods. Between each rod 18 leaves like lotus leaves with revolving keys should be fixed. The instrument is to be shaped like an umbrella. The leaves should be fixed at the pivot top with 8 keys.
When the burning flames are imminent, the pilot should turn the expansion wheel vigorously, and the umbrella will open up and provide a shielding cover for the vimaana. The lotus petals, the crystals, and the enveloping cover will protect the vimaana from the threatened danger.
According to "Gati-nirnaya-adhyaaya" In the Aavaha and other giant wind spheres there are 122 kinds of different motions of the wind. In the summer season the 79th kind of motion occurs mostly. When the vimaana travels in the 4th region of the sky, it tends to zig-zag owing to the wind currents, and cause hardship to pilots and other occupants. Therefore as a safe-guard against it, the Vaatastambhana-naala-yantra should be installed in the bottom section of the vimaana.
Says "Yantra Sarvasva",
The vaatastambhana naala yantra should be manufactured with the vaatastambhana metal only.
According to "Lohatatva prakarana," dantee or croton seeds, suvarchala or sun-flower salt, mayoora or sulphur, lohapanchaka or copper, brass, tin, lead, and iron, bhrisundika, suranjika or sulphate of mercury, varaahaanghri loha, virohina or creya arboria, kuberaka, muraarikaanghri metal, ranjika or phosphorus, suhamsanetraka, dala or folia malabathy, courie sea-shell, mrinaalikaa or lotus stalk, to be powdered, cleaned, and in equal quantities filled in matsya or fishshaped crucible, and placed in maaghima furnace, and with the aid of vijrimbhana bellows duly melted, will yield a molten liquid which when poured into the mould and cooled will yield an excellent vaatastambhana loha.
With that metal 6 naalas or tubes of 15 inches diameter, with wide openings should be prepared and fixed in the tail and centre and front of the vimaana 10 inches deep, east to west and north to south, and held together with hoop iron binders. At the mouth of each tube a vaatapaa or air imbibing crystal should be fixed by wires. Between the tubes flags or pennants made of cottoncloth duly processed, should be tied. And wheels made of the special metal should be fixed above each pennant. When the vaataayanee wind blast blows, the pennants will flutter noisily, and the wheels fixed underneath them will also revolve as also the crystals. The fluttering pennants pass the blowing wind to the wheels which pass them on to the crystals, which will pass them into the tubes from which they will be ejected through openings to the outside. That will protect the vimaana from their interference.
Sowdaaminee kalaa explains it as follows:
During the rainy season, when rain clouds gather in the sky, lightning of five kinds begin to play.
They are named vaaruni, agnimukha, danda, mahat, raavanika. Of them, vaaruni and agnimukha are very active and fearful and are likely to be attracted by the roudree-darpana and other mirrors and cause fires which destroy the vimaana. In order to prevent that the vidyud-yantras should be installed in the front and the right side of the aeroplane.
According to Yantra-Sarvasva:
In order to protect the plane from lightning, vaaruni and agni, the vidyuddarpana should be installed in the vimaana.
Darpana Prakarana explains its structure:
Kuranga or pallatory root, panchaasya metal, virinchi, shonaja or red lead, sand, alum, kutbha or hellebore, pearl, sundaaliga, mercury, yavakshaara or salt-petre, borax, bidouja salt, pingaaksha or terminalia chebula (?), cowries, and karbura or hedychum specatum, powdered and purified, in the proportion of 10, 7, 4, 3, 12, 2, 3, 7, 11, 27, 14, 3, 22, 18, 5, and 11, filled in padmaasya crucible, placed in vishvodara furnace, and with the aid of the 5 mouthed bellows heated to 500 degrees, the molten liquid will yield in the cooling mould a glass which is impregnated with 300 shaktis or forces, and can overpower the lightning blasts from the vaaruni and agni forces, shining with wonderful rays, and capable of spreading its own lighting force within 2 kshanas or a few seconds to a distance of 5 yojanas or 15 miles.
With that lightning darpana glass should be constructed the Vidyuddarpana yantra. A plank, 20 feet in diameter and 1 foot high, square or circular in shape should be prepared, 4 glass tubes of crescent moon shape should be fixed around the peetha or plank. In the centre should be fixed a cage made of chumbuka glass, fitted with wires and 5 faced switches at each face, and 5 goblets made of vidyuddarpana. In the centre should be fixed a spire made of the same glass with 7 cross spokes and tubes, 8 faced and 10 angled. By turning the key inside, the spire is to revolve with speed. That will attract and contain the lightning emitted by the clouds. The rays will expel it to the outer air region, and incapacitate it. Then a snow-like cool temperature will render the interior of the vimaana safe and pleasant for the pilot and other occupants. Therefore this vidyuddarpana yantra should be installed duly in the vimaana.
"Kriyaasaara"' says-The spots from which sounds emanate in the sky are called shabda-kendras or sound centres.
The different directions from which the sounds p. 62 are projected are called shabda-kendra mukhas. The yantra which is meant to control the sounds so projected is called shabda-kendra mukha yantra.
Out of 304 classified sounds the sounds of water-laden clouds, wind, and lightning are said to be fiercest. In the 8th region of the sky these three sounds unify in the shishira Ritu or FebruaryMarch period, and produce ear-splitting thunders. They would deafen pilots and others in the vimaana. As protection against that the shabda-kendra mukha yantra is to be installed.
It is said in Shabda-nibandhana, "By the combination of water, fire, air, and sky, sound is generated both among living and life-less objects. The sounds in the word "Shabdaha," i.e., sha, b, d, and ha, indicate water, fire air, and sky symbolically."
"Naamarthha-kalpa" says, We shall deal with the nature of sound or "shabdaha". The word consisting of sounds sha, ba, da, and ha, stands for water, fire, air, and sky. By the combination of these four forces in various proportions, 304 different kinds of sounds are generated.
The Braahmana bhaaga of the Veda also says shabdaas are of 304 kinds, such as sphota or embryo, very feeble sound, feeble sound, manda or soft, very soft, fast, very fast, medium, very medium, great sound, thunder sound, and thunder-bolt sound.
It is said in Yantra-Sarvasva, In the 8th region of the sky, by the concatenation of water-cloud, wind and fire, an extremely fearful thunder clap will occur which will blast the ears of pilots who may enter the region. To safeguard against that the vaataskandha mukha yantra is to be installed in the vimaana.
In the 8th region of the sky there are 307 centres of sound. From the 70th centre a fierce sound proceeds by the force of water. From the 312th centre a fierce sound produced by wind will emanate. Similarly from the 82nd centre a fierce sound generated by lightning will emanate. By collision of the three a terrible sound will result which will deafen the pilots of the vimaana.
Therefore facing each sound emanation centre the shabdopasamhaara yantra is to be established.
The construction of the yantra is as follows:
Gavyaarika, monkey's skin, duck-weed, shana-kosha or jute product, crounchika or lotus stalk, vaaripishtaka or shag, roonthaaka, flesh, elephant trunk, and tin, are to be purified, and the nine elements, other than the skin, in equal parts, filled in niryaasa yantra and baked for 3 days with buffalo bile, will yield a decoction of fine scarlet colour. Seven times this decoction should be spread on the skin, and left to dry in the sun. The skin will then acquire the capacity to suppress sound.
A box 2 feet long and 1 foot high made of badhira or deaf metal is to be made. Two pipes made of the same metal shaped like crane's beak, should be fixed inside it. Above it should be fixed an umbrella made of shabdapaa darpana, or sound-drinking glass. A crystal washed with tulasee or basil seed oil should be placed inside the monkey skin and sealed with rhinoceros gum. The sealed skin with crystal should be placed in the central pipe inside the box. Monkey skin alone should be placed in the pipe on the left side. Thin wires should connect them all and be fitted with hinges and switches. Above the canopy of the box a monkey skin shaped like lion's mouth should be connected by wire through a pipe to the crystal in the tube inside the box. The top of the box should be covered, securely.
Badhira loha or deaf-proof metal is explained in Lohatantra-Prakarana; lime fruit, laguda or sweetscented oleander, virinchi, rishika or water-calteop, maaloora or Bengal quince, panchaanana metal, luntaaka, varasimhika or solenum xunthokurpum, kuravaka or gigantic swallow-wort, sarpaasya or mesua ferrea, vaakula or surinam medlar, jack-fruit, camphor and vatika or salvinia cusullata, in equal parts, purified, and filled in tryutee crucible, and heated in the furnace, will when cast produce a metal, cold, dark, sound-proof, powerful, able to control bleeding, and draw out missile parts from the war wounds of soldiers and healing them, and capable of reducing the effect of thunder claps.
The simhaasya bellows is to collect the fierce sound and transmit it to the crystal inside the metal box so that the monkey skin will absorb it and stifle its intensity. Therefore shabda-kendra mukha yantra should be installed in the vimaana.
p. 64 Vidyud-dwaadashaka Yantra, or Yantra of 12 lightnings is explained in Kriyaasaara.
In the realm of the comets and shooting stars in the sky, at the 8th region there are 30703221 shooting stars. 8000 of them are prone to lightnings, and 12 of them known as mahaakaala etc., are of importance.
