According to "Yantra sarvasva," its parts are, peetha or pedestal, pillar, tubular pole, electric wiring, glass lotus petals, lotus formation process, places where the lotuses are to be located, wind inhaling and leather-bellows mechanism, contracting and expanding switches, triple-wheel fixing arrangement, air flow outlets, folding up mechanism. These are the 12 parts of the padmachakra mukha yantra.
The peetha or seat should be made of the wood of pippala or the holy fig tree, 8 feet and 3 feet high, and square or circular. Mark 12 fixing centres on it. From the central pillar draw lines towards the 12 spots. The central pole, two tubular posts on either side of it, electric wire in eastern centre, p. 45 lotus petals in the north, formation of lotus in the northern and southern centres, fixing of the lotuses from the north-east to the south-east corner, to the east air-filling bellows. In the north west corner the contracting switch, and the expansion switch in the south-west corner, triple-wheel revolving mechanism on the eastern side, air flow outlets underneath each lotus. To its south, the contraction switch.
These are the 12 parts to be fixed in the 12 centres. The production of the parts is as follows:
The central pivot should be made of abhra-mrid-darpana, or mica-sand glass. According to "Darpana-prakarana"-parts of rambhasatva (plantain stem?), 8 of manjoosha (madder root?), 5 parts of kaanta (ayaskaanta? sooryakaanta?), 8 parts of kravyaada (jataamaamsi), 3 parts of aadhaka essence, 7 parts of tortoise shell essence, 18 of bhalyatvak, 3 essence of kudmala or flower buds, 8 of bamboo salt, 3 of hooves, 28 parts of shoonya-mrid or mica ash, 4 of trivikrama kshaara, 2 of conch, 5 of mercury, 8 of salts, 1 of creepers, 3 of silver, 3 of eye-ointment, these 18 ingredients, purified, filled in crucible, placed in varaatakunda furnace and boiled to 200 degrees, and slowly filled in darpana yantra, will yield an excellent abhra-mrid darpana.
Two tubular poles of the size of an arm, made of this glass, should be placed on either side of the pivot. From the central pole electrical wiring should be connected to the 12 centres. In the centre of the switch tubes should be placed the lotus petals, and 150 finely made glass lotus petals should be spread on the northern side electric wires.
The petals are to be made, according to Lalla, by mixing 15 parts of the mica glass, with 4 parts of sourika salt, duly mixed and finely powdered and melted in pattikaa machine, when like onion-skin layers, petals will take shape. Then the wires attached to the petals should be brought together from the several centres, and attached to the lotus forming mechanism. By turning the concerned wheel the petals will move towards the centre and form a lotus. Each petal will then become a tube, and by their juggling each p. 46 tube will form 2 petals. The air-attracting mechanism should be placed in front and set to work.
With a shrieking noise the air will be sucked in by each tube and the petals will shoot the air far into the outer air.
It is said in "sandhaana-patala--" The scattering of a blizzard which may obstruct the progress of the vimaana is only possible by means of the padma-sandhaana and not otherwise. Therefore the spots where the lotuses are to be inserted are now indicated. On the eastern side from the north east to the south east the lotuses are to be erected in seven places in close order. Beneath the seven lotuses should be fixed seven leathern bellows capable of deep draughts of air. On the north west corner should be fixed the double-wheeled contracting mechanism.
According to "Kriyaa saara," by turning the main wheel in right motion, and the upper wheel in reverse motion at full speed, the yantra will suffer contraction. This machine is composed of 6 wheels spread out, 5 naalaas or tubes, 12 wires and 12 openings, and 12 keys which will cause contraction of the 12 parts, with widened mouth at the upper and lower parts, and provided with 2 revolving keys. By placing such a contracting machine in the north-west corner, the machine could be contracted when desired.
Now we shall deal with the expanding mechanism. It is round like a water pot, with 12 wheels and mouths, having 12 tubes with rods inside with 12 revolving springs for ascending motion, and with a central spring for filling with air. With such a mechanism the yantra can be made to stretch its parts. This should be fixed in the south west corner.
Then at the eastern face the triple-wheeled revolving spring, called "bhraamanee-keelaka", should be fixed.
It has 3 ivory wheels, consists of 3 poles, wooden top shaped like shimshumaara, with wheels with spring on top. By its operation the several parts of the yantra are set in motion, and by the operation of the concerned springs, the yantra will expand. Therefore the 3 wheeled bhraamanee mechanism should be properly fixed at the eastern kendra with 5 bolts.
Underneath the lotuses air flow routes should be provided. There should be openings 12 inches wide, 2 inches high, be leather-covered, made p. 47 of pippala wood, with 7 tubes for the flow of wind. Seven such tubes should be fixed beneath the seven lotuses, and provided with keys.
In the southern centre the contracting mechanism or upasamhaara keela, with 12 outlets, should be fixed.
Owing to the seasonal changes forces will generate in the joints of the outer space, and combining with the oceanic forces will reach the realm of air and cause a commotion which will spread out with fierce force into the farthest air pockets, and let loose typhoons which reach the vimaana, and produce a dusty excrescence which will induce chicken-pox-like skin eruptions on the pilots and other occupants, and also break up the vimaana. In order to suck up that foul windflow, and expel it out of the vimaana, the padma-patra-mukha yantra is prescribed.
Now we shall deal with kuntinee-shakti yantra. In mid-summer, out of the myriad heat rays of the sun, by the union of the 3, 5, and 10th class of rays, a fierce force of blazing heat named kulakaa is generated.
It is said in "Ritukalpa", From the solar heat generative source 3 Mahaakshoni and 21 crores 500 lakhs 16 thousand and nineteen heat rays emanate. They are classified into 5 crores 8 thousand and 107 groups in Vaalmeeki ganita. Each group is divisible into 100 sub-groups. Of these when the rays of subgroups 3, 5, 10 from the second group get mixed up in the heart of summer, a force called Kulakaa with fiery intensity is generated; and when it moves into the path of the flying vimaana, the plane will be reduced to ashes. To protect against that the kuntinee-shakti yantra should be installed in the neck portion of the vimaana.
Sage Narayana also says:
Amongst the divisions of the heat rays of the summer sun, the second group has 85000 rays. Out of them those numbered 8, 3, and 10 are specially intense, and they attract the pramlochana shakti from koorma portion of the universe, and produce a fierce heat-wave called kulikaa. If a vimaana happens p. 48 to encounter it in its course, it will be burnt to ashes. To safeguard against that the kuntinee-shakti yantra should be installed in the neck section of the vimaana.
Lallaachaarya also confirms:
Out of the many groups of the heat-rays of summer, numbers 3, 5, and 10 in the 32nd division of the 2nd group of rays' tend to contact the pramlochana shakti in koorma and produce a fierce force called kulakaa which will destroy the vimaana. The erection of the kuntinee-shakti yantra in the vimaana will prevent it from such destruction.
According to "Yantra Sarvasva",
Among the constituent yantras of the vimaana, the kuntinee-shakti yantra is required to protect it from the combustible heat waves known as kulikaa in summer. Its parts are ground-plate, central switch-board, acid vessel cloth, with folds, chakradanti naala, milk cloth, tube covering switches, revolving wheel equipped with electric wiring, and contracting mechanism.
The peetha or ground-plate should be 3 feet wide and ½ foot high, and round like a drinking bowl, seven kendras or centres commencing from the eastern side, turning switches in the seven centres, the acid vessel in the central kendra.
For capturing kulikaa the oil from gunja or the seeds of the shrub abrus and tobacco leaves, and mercury and shanaka crystal are recommended for use. The oils or acids of the seeds and tobacco leaves are to be filled in goblet like cup made of glass made of naaga, crownchika, and sowrambha metal, add purified mercury, and fix in the central kendra. Then apply the solar rays to the vessel. By the action of the rays on the acids the crystal in the vessel will become charged with a cold frigid force called krownchinee. Then when the kulikaa force enters the vessel with its fierce heat, it will be sucked in by the cold-storage crystal.
In the left kendra the cloth with folds should be fixed. Says "Patakalpa.--"p. 49
In order to confine in the crystal the fierce heat of kulikaa it should be wrapped in the folds of a cloth of fine and strong texture made of spikenard and jute yarn, with 5 folds and 3 openings.
From the openings 3 glass tubes should be projected with downward bends into 3 wide mouthed vessels. To the north--east must be fixed the chakradanti naala for attracting the kulikaa force.
Snake-skin, gum of srini, woollen yarn, soft grass, should be boiled together and lac-coloured cloth-like glass prepared, and purified with sundikaa wood oil. It should he rolled in coils just as a snake circles up in coils and sleeps. The tiny glass tubes should be attached at the bottom of the chakradanti as directed.
Then ksheeree-pata naala, or milk-cloth tube is to be fixed. Made of milk-cloth with wide-opening, strong, soft, a tube should he inserted in the mouth of the chakradanti, and its end should be made to reach the hole in the peetha. Through that the kulikaa force makes its exit. After placing ksheeree pata naala like this with key, the electric wire connected central operating switch should be placed in the west. And to the north-east of it the vistritaasya or opening out switch should be fixed.
It should have two satchels, two openings, two right-revolving and reverse-revolving wheels. In the eastern opening should be fixed the 2 right-revolving wheels. And in the northern mouth should be fixed the 2 reverse motion wheels. And as in an umbrella, sticks connecting all the parts with the centre, for the purpose of expansion and contraction by turning a switch. By operating the switch in the eastern opening all parts will open out or expand. By operation of the northern switch all parts will close up. This is the upasamhaara keelakaa.
Having enumerated the parts of the yantra, their operation is now given. First the electric switch.
By putting it on, the Bhraamanee chakra or pivotal wheel will revolve setting in motion individual parts as and when desired by turning their respective switches. Then electric current should be passed to the acid containing the crystal. Solar rays also should then be passed into it. Thereby, in the acid there will be generated a female shakti of 5 nyankas called sowlikaa. Similarly in the crystal there will be generated a male shakti of 8 nyankas called chulikaa. By operation of the electric p. 50 current the two shaktis will get unified and produce an extremely cold shakti called "crownchinee," capable of attracting the kulikaa. That crownchinee force should be projected through naala or tube towards the kulikaa, like imbedding a gunja pea in a lump of lac. Thereby the crownchinee will drag the kulikaa inside the yantra through the tube and drop it into the acid vessel where it will be imbibed by the crystal.
Then the patormikaa key should be turned, whereby the patormikaa will become wide open preventing any air from entering the crystal by covering it completely. Then the chakradanti key should be turned slowly, so that its mouth opens out and sucks the hot kulikaa from the crystal, and stores it inside itself. Then the key of the sookshmaadarsa naala, fine mirror tubes, should be operated. The kulikaa in chakradanti will emerge through the 3 tubes. Then the vistritaasya key should be operated quickly so that all the parts will open out, and the kulikaa shakti will get out and disappear, and the danger to the pilot will have passed. Then by operating the upasamhaara keelaka, the expanded parts will close up and the yantra will return to normalcy.
Now we shall deal with Pushpinee yantra. When the pilot has to travel during spring and summer months, the pushpinee yantra is intended to provide him with necessary comforts.
According to "Khetavilaasa":
In spring a force called sowrikaa emanates from the south-east. And in summer a force called panchashikhaa arises in the north-west and is intensified by the sun's rays. Panchashikhaa contains two kinds of poisons. Sowrikaa having fire and moon contents is cold and hot, cold internally, and hot externally. It generates warmth in all creations, making the human kind perspire, and the trees and vegetation bring out their milk and gums. Thereby their bodies are relieved of harmful materials likely to lead to diseases.
By its cold effect and attracting the spring effect from the solar rays, it permeates all things, and brings out shoots, tendrils, flowers and a glow in all trees and creepers. Similarly it effects the 7 physiological components of the human body and increases their vigour, strength, growth, and glow.
p. 51 Panchashikhaa shakti or force effects movable and immovable life adversely by its stultifying influence, shrinks and dries up the growth process of both vegetable and animal life and causes deterioration. To counteract this harmful effect of the season on the personnel of the vimaana, the pushpinee yantra is commended as one of the constituents of the aeroplane.
Its parts are, the base, the cold processing mirror, keelaka or key, cold generating crystal, acid vessel, electric wheel with 100 spokes.
