mercury, these 15 ingredients are to be mixed in the proportion of 5, 12, 4, 3, 7, 3, 11, 4, 9, 12, 20,
18, 12, 5, 20. The mixture should be filled in the crucible known as samavargika, and heated in
the furnace of the same name, and heated to the degree of 315, with the aid of bellows called
suraghaa. The resulting liquid should be poured into the mirror--making machine. The resulting
product will be a fine bimbaarka-kiranaadarsha, or reflected solar ray attracting mirror. This should
be fixed in the central portion of the vimaana and in the 10th kendra, with five circled screws.
Now we deal with the crest crystal of the vimaana. The crest-crystals are of 103 kinds. They are
named in "Mani-kalpa-pradeepika" as belonging to the 12th class of 32 groups of crystals. Their
names are shankara, shaantaka, kharva, bhaaskara, Mandana, kalaantaka, deeptaka, nandaka,
chakrakantha, panchanetra, Rajamukha, Raakaasya, kaalabhyrava, chintamani, koushika,
chitraka, bhaskara, uduraaja, viraaja, kalpaka, kaamikodbhava, panchasheershna, paarvanika,
panchaaksha, paaribhadraka, isheeka, kaashabhrit, kaala, kanjaasya, kowtika, kalaakara,
kaarmika, vishaghna, panchapaavaka, symhikeya, roudramukha, manjeera, dimbhika, pingala,

These are the 103 crystals suitable for being fixed as crest-jewels of the vimaana. One of them is
to be fitted to the central pinnacle at the top of the vimaana, and the wires from the electric
dynamo should be connected to it, so that it might be supplied with power. On the upper side
should be attached wires for collecting solar rays, so that the two forces might act in combination.
The switch-gear for connecting the vimaana with the solar energy is explained in "Brihath-
kaandika." Sandhaana-keelakaas are of 25 kinds. Their names are pinjuleeka, keeranaka,
dimbhaka, paarvateeyaka, kachchapa, gaaruda, uddanda, shaktipa, govidaaraka, pavanaasya,
panchavaktra, vajraka, kankana, ahirbudhnya, kundalika, naakula, oornanaabhika, trimukha,
saptasheershanya, panchaavartha, paraavatha, aavarta, naabhika, oordhvaasya, shilaavarta.
Amongst these the 9th, govidaaraka, is best suited to connect the vimaana with the solar beams
for safe navigation. This is Pariveshakriyaayantra.
Next Angopasamhaara yantra:
During the passage of sun and other planets in the 12 houses of the zodiac, owing to the varying
speeds of their progressive and retrogressive motions, conflicting forces are generated in the
zodiacal regions, and their collisions will let loose floods of fierce forces which will reduce to ashes
the parts of the plane which get involved with them. The pilot should get warned by the ushna-
pramaapaka yantra, or heat-measuring instrument, and quickly fold the concerned parts and
ensure their safety.
