கிரகங்களின் அவஸ்தை - பிருஹத் பராசர ஹோர சாஸ்திரம்

30-37. Calculation of Shayan Adi Avasthas. Now I will tell you of the Avasthas, viz. Shayan, Upavesan, Netrapani, Prakash, Gaman, Agaman, Sabh, Agam, Bhojan, Nritya Lips, Kautuk and Nidr and the Chesthas of such Avasthas. Note the number of the star, occupied by the Grah, for which an Avastha is to be calculated. Multiply that number by the number, denoted by the Grah (Surya 1 to Sani 7). The figure so arrived at should again be multiplied by the number of the Navans, where the Grah is in. Add to this the number of the birth asterism (ruling star, the one, occupied by Candr), the number of Ghatis of birth and the number of Rasis, Lagn gained from Mesh (Mesh 1, Vrishabh 2 and so forth). This figure should be divided by 12 and the remainder will indicate the corresponding Avastha of the Grah. The sub-state in the said Avastha can be found out in the following way. Multiply the figure (Sayan 1 to Nidr 12), denoted by the Avastha concerned, by the same figure and increase it by the figure, denoted by the Anka value for the first syllable of the native’s personal name. Divide the product so obtained by 12. The remainder thereof should be further increased by constant additives of the Grahas in the following way: Surya 5, Candr 2, Mangal 2, Budh 3, Guru 5, Sukr 3, Sani 3, Rahu (Ketu) 4. The product so arrived at should be divided by 3. In the process of calculation, if it happens, that the remainder is 1, it is Drishti, if 2, it is Chesht and, if 0, it is Vichesht.

Notes. Shayan Adi are of supreme importance, as compared to the other kinds of Avasthas.

In place of Navans, given above, some translators interpret the word Ans, as degree, occupied by the Grah, which is obviously not correct. In this connection the reader’s attention is drawn to Balabhadr’s Hora Ratna, Ch. 3, wherein the author, Balabhadr himself, gives an example for Surya, being in the 7^th Navans of Simh and thus he considered only 7, as multiplier. He quotes Adhibhut Sagara, as his authority for calculation of Sayan Adi.

Agaman Avastha is known, as Gamanechch by some exponents.

Anka value is 1 for a, ka, cha, ḍ a, dha, bha and va, 2 for i, kha, ja, ḍha, na, ma and sha, 3 for u, ga, jha, ta, pa, ya and sa, 4 for e, gha, ṭ a, tha, pha, ra and sa, 5 for o, ca, ṭha, da, ba, la and ha.
