Then get a Jyotirmukha or flame-faced lion's skin, duly cleaned, add salt, and placing in the vessel containing spike-grass acid, boil for 5 yaamas or 15 hours. Then wash it with cold water. Then take p. 98 oils from the seeds of jyothirmukhee, or staff-tree, momordica charantia, and pot herb, in the proportion of 3, 7, and 16, and mix them in a vessel, add 1/64 part of salt. The skin should be immersed in this oil and kept for 24 days in solar heat. It will get a scarlet sheen. The skin should be cut to the size of the top opening of the vessel cylinder, with 5 openings in it. Cover the cylinder with the skin with bolts. All the 5 vessels should be similarly covered, and placed in the 5 selected centres on the peetha. Then 16 drona measures of asses' urine, 16 linka measures of mined charcoal, 3 linkas of salt, 2 linkas of snake-poison, and 2 linkas of copper, should be filled in the vessel on the eastern side.
Then in the vessel on the western side, 7 vidyudgama mani or load-stone, 13 praana-kshaara or ammonium chloride, 22 hare-dung, should be filled. and made into a decoction. Two parts of camel urine should be mixed with one part of the above. Then 50 linkas of rhinoceros bones, 30 linkas of sulphur, and 16 linkas of tamarind tree salt, and 28 linkas of steel should be added to that.
And 117 tatin-mitra manis should be placed in the centre of the vessel.
Next the following materials should be filled in the northern vessel:
Eleven parts of oil of apaamaarga or achyranthus aspera seeds, 32 parts of oil seeds of sarpaasya or mesua ferrea, 40 parts of ayaskaantha or oil of steel, in 83 parts of elephant's urine, all these to be put in the northern vessel and mixed together properly. Then add mercury, symhika salt, and paarvanika or bamboo rice, 30, 20, and 25 palas respectively, or 120, 80, and 100 tolas.
Sun-crystal of the 800th type, mentioned in Maniprakarana, cleaned in oil, should be put in the vessel.
Next in the vessel on the southern side, put in grandhika draavaka or long-pepper decoction, panchamukhee draavaka, and shveta-punja or white liquorice decoctions, in proportion of 12, 21, and 16, and mix together, add cows' urine 5 parts more than the above liquids, 47 parts of jyotirmayookha root, 28 linkas of kaanta metal, 28th and 10th kind of kudupa 32 parts. 92 jyotirmanis purified in milk should be placed in it, according to Chaakraayani. This is the southern vessel.
Then in the central vessel electric current should be stored. That vessel should be made of chapala-graahaka metal only.
Chapala-graahaka metal is explained in Lohatantra:
Quick-lime, marble stone, lac, sowraashtra earth, glass, root of the elephant trunk tree, bark of karkata tree, cowries, cubeb pepper gum, in the proportion of 8, 11, 7, 27, 8, 5, 3, 7, and 12 parts of tankana or borax, to be filled in urana crucible, placed in kundodara furnace, and with 3 faced bellows, boiled to 427 degrees, will yield, when poured into the cooler and cooled, chapalagraahaka metal.
The electricity storage vessel should be manufactured as follows: A foot-plate 5 feet long, 8 feet high, 1 foot thick, half-moon shaped, should be made of above metal. The vessel should be shaped like a big pot, with a cylindrical top. It should have a glass covering. 2 pipes 3 feet wide 6 feet high should be fixed in the vessel in the northern and southern sides. They should also be covered with glass. Between the two pipes two wheels with hinges and switches etc. should be fixed. When the switches are put on or turned, causing the two wheels to revolve, electricity will flow from the bottom of the 4 vessels into the two pipes and ascend. Two tubes, 6 inches long, should be prepared, wound round with deer skin, tied with silk thread or silk cloth. The Vajramukhee copper wires cleaned with acids, should be passed through each tube, and taken to the two pipes in the vessel and be fixed with glass cups. 8 palas or 32 tolas of mercury should be placed in the energy container vessel. 391st vidyunmukha mani, wound round with copper wiring with mixing switch, should also be inserted. Then taking the wires in the pipes they should be connected with the wiring of the mani through the kaachakanku hole. In each of the vessels, excepting the middle one, two churning rods should be fixed in the centre. The rods should be made of steel or shakti skandha. They should be 3 feet high and 1 foot thick. Keys should be fixed in them for obverse and reverse churning. To the east of the churning machine wheels should be fixed for raising and lowering. An 8 inches high naala or tube should be fixed. On either side of it should be fixed 5 wheels of 5 inches height, like the wheel of the water lifting machine. 2 inches wide flat pattis made of shakti skandha metal should be passed from the wheels inside the Aavritta-naala to the keys of the wheels in the churning yantra. Then revolving wheels should be attached to the naalas or tubes of the stambha or big pipe. By the turning of these keys, it will operate like the turning of the churning p. 100 rod back and forth as in churning curds by drawing and relaxing the rope ends.
Then according to Darpana-shaastra, four vessels, shaped like the bamboo cylinder used on the pounding mortar, should he made out of ghrinyaakarshana glass or solar-heat absorbing glass and fixed on the mouth of the 4 vessels.
The vessel is described by Lallaacharya: 8 inches wide and 1 foot high, and then 2 feet wide and 6 feet high, and at the top a 6 feet wide mouth.
25 palas or 100 tolas of bamboo salt, should be put in it. Then amsupaa mani or solar-ray crystal of the 325th kind, duly cleaned in acid, should be put in it with rice salt. Then rice hay should be spread over it tightly, and facing the sun. The rays from all sides are imbibed by them, and will enter the vessel daily to 105 degrees' strength. If kept thus in the sun for 12 days, 1080 linkas of electric power will be accumulated in each vessel.
In order to store this power in the storage vessel six inches long steel tubes should connect the bottom of the vessel with the storage vessel. They should be covered by deer skin and wound round with silk cloth or yarn. Two copper wires should be passed through the tubes and connected to the storage vessel. 100 palas of mercury should be put in the vessel. And a 391th type of sun crystal duly wired should be placed in the mercury, and the wires coming from the tubes should be connected to it.
The well-oiled keys in the 4 vessels should be revolved with speed, to 200 degrees heat, when the liquids in the vessels will be boiled by the heat rays. Then the keys should be hastened up to 2000 degrees. By the liquids in each vessel 800 linkas of electricity will be generated. The power should be conveyed by the wires in the kaanta metal tubes to the storage vessel. The crystal will absorb and fill the vessel with the power. In front of the storage vessel a five feet long, 3 feet high circular vessel should be installed. It should be covered all round with the bark of vaari-vriksha.
p. 101 Always water will be flowing in it. So instead of water, water skin is indicated. It will give the vessel the effect of water-immersion. Then in that vessel glass cups containing the decoction of shikhaavalee or lead-wort? or achyranthes aspera?, 18 parts of ayaskaanta or loadstone? or steel acid?, and 12 parts of vajrachumbaka acid, should be placed. Then power should be drawn from the storage vessel through the wires inside the glass-covered tube, and 4 wires with glass wheel key be let into the acid vessels. Then from the bottom of the vessels 2 wires fitted with keys should be taken in a right circle to the front of the smoke-outlet stambha or pipe, and attached to the wires inside the bhujyu metal tube. The wires should also be connected to the keys of the electric friction crystals in the dhoomodgama stambha or pillar, as also to the key in the stambha.
Thereby electricity will be spread in all parts of the vimaana. Therefore the vidyud-yantra or electrical machine should be installed in the left side of the vimaana.
In order to enable the vimaana to ascend, vaataprasaarana yantra is necessary.
Therefore it is now being described. It should be made out of vaatamitra metal only.
Lohatantra describes vaatamitra loha. 13 parts of rasaanjanika or extract of Indian berbery, 27 parts of prabhanjana, and 37 parts of paraankusha, should be filled in sarpaasya or serpent-faced crucible, placed in chakramukha furnace, and with the aid of vaaranaasya bhastrika or bellows, heated to 216 degrees. Then filled in the sameekarana yantra or churner, and next poured out and cooled, it will yield vaatamitra loha, or air-companion metal.
First the foot plate, then the naala-stambha or tubular pole, air pumping wheel with keys, air attracting bellows-like mechanism, and mechanism for contracting and expanding the mouth, outflow and inflow tubes with keys, covering for the yantras, wind pipes, vaatodgama p. 102 pipe, bhastrikonmukha, vaatapoorakeelakas, vaata nirasana pankha keelaakas, or air-expelling fan keys, these 12 are the organs of the yantra.
The 3 wheeled naala stambha is described in "Yaana bindu":
Three feet long and 8 feet high tubular poles should be fixed on 2 sides of the peetha or foot-plate.
At the foot and the middle and the top of the pole three openings should be provided for fixing 3 wheels.
In the pole should be fixed tubes, one foot wide and 2 feet long, for drawing in air, and wheels 1 foot wide with teeth as in hack-saw, revolving both ways, be fitted to the tubes. The vaata-pooraka or air-filling naala should be fixed in the middle of the wheel. By turning the fly wheel, the wheel will turn, making the naala move up and down sucking in air. The air pumping wheel keys should be thus fixed in the two poles. The keys at the mouth of the bellows should be connected to these keys.
Taking pig-skin, duly cleaning it with putrajeevi or wild olive oil, boil it for 3 days, wash it with clean water. Smear it with gajadantika oil frequently exposing to sun for 5 days, and fashion out of it a 6 foot bellows, three feet wide at bottom, 4 feet wide in the middle, and 1 foot wide at the mouth.
Two keys working conversely to each other should be fixed at the mouth. A stick should be inserted between them. The two keys should be capable of being put into quick motion, or left at rest. By turning the keelakas the piston rod is moved, and from its speed, the bellows' mouth also will start in motion, and also the vaataakarshana naala. By putting the naala at the mouth of the bhastrika or bellows, quick air entry from inside the mouth will occur. By starting all the keelakaas in all the centres there will be airflow in the three wheel tubular stambhas. By turning the p. 103 keelakas with 20 heat-degree force, in the naala stambhas air will rush out with 100 shaker speed.
From the bellows' mouth also air will blow with 2000 prenkhana or shaker speed. And these air flows will speed the motion of the vimaana. Therefore in front of the vaatodgama yantra 12 such yantras should be installed on the four sides, 3 on each side. And aavarana or covering should be provided for them according to their measurements. And 12 naala stambhas, 3 feet wide and 12 feet high, should be prepared, and fixed on the top covering of the yantras, for the air to flow out.
From each stambha air will blow with 2600 prenkhana speed. The yantras are individually prescribed so that some may rest when not required. The high flight will be helped by these machines. Having thus described the individual sources of air supply for the vimaana, we shall now describe the Brihat-stambha or main mast.
It should be 4 feet wide and 30 feet high, and called vaatodgama naala stambha. It should be erected centrally amidst all the yantras. The bhastrikonmukha yantras should be fixed at the foot of the stambha so that the air flows from the yantras could pass into the stambha. The windnaalaas or pipes should be connected to the stambha-moola fitted with keys. At the opening of the naala-stambha at the top on the 8 inch wide opening a vessel one foot high and 3 feet wide should be fixed. The wind from the stambha or tunnel will pass out through it in wavy billows. The dhoomodgama yantra or smoke pipe should, be provided with triple keys or fixtures, for the expulsion of smoke. and blowing in of air. By operating those keelakas the supply of smoke and air could be controlled according to need. Wind expelling fan wheels should be put in, so that by their quick motion the motion of the vimaana could be facilitated.
Covering the dhoomodgama yantras and kudyaas or side walls, as in the case of the Shakuna Vimaana, the covering of the Sundara vimaana should be done by raajaloha only. The covering should accommodate the number of partitions or booths required as in Shakuna Vimaana. The location of the 32 component yantras should be determined.
p. 104 In the centre of the booths for locating the four-faced heat machinery, a thirty feet [paragraph continues] square area should be set apart.. There the four-faced heat yantra should be erected.
The chaatur-mukha owshnya yantra should be made out of kundodara metal only. Kundodara metal is defined in Lohasarvasva.
Soma, Kanchuka, and shundaala metals in the proportion of 30, 45, and 20 to be taken, cleaned and filled in padma crucible, placed in chhatramukha furnace, and with vaasukee bellows heated to 716 degrees, aa-netraanta, and poured into the yantra for cooling. A blue, fine, light, alloy, capable of bearing 2000 degree heat, and which cannot be blasted even by shataghnee and sahasraghnee canons, and very cold, is kundodara alloy. With this alloy the owshnyaka yantra should be fashioned.
Yantraangas or parts of the Machine.
Peetha or foot-plate, smoke container kunda or vessel, water container, fire oven, turret covering, covering of water container, twin wheels for projecting and restraining smoke, window rods, padmachakras or wheels, aavritta chakra keela, heat indicator, speedometer, time clock, ravaprasaarana keelaka naala or sound transmitting instrument, antardandaaghaata naala, airbellows, long sundaala pipes, twin copper pipes, air dividing wheel keys, these 18 parts constitute the ooshmyaka yantra.
