बृहत्संहिता (आचार्य वराहमिहिर - स्थापत्य, खगोल, मौसम व जल विज्ञान)

732 बृहत्संहितायाम् [Adh. XCVI. Sl. 12-13.
14. In reconstructing a name, the method to be adopted is
the following: Take the four Kendras beginning with the first
sign (i. e., Aries, Cancer, Libra and Capricorn) and their Navam-
sas in regular order for the first; then take the letters of the
classes belonging to the respective planets owing to their position
in the Navamsas identical with the above ones.
मेषे ककारो हिबुके यकारस्तुले चकारो मकरे पकारः ।
मेषे छकारो हिबुकेऽप्यकारस्तुले खकारो मकरे फकारः ॥ १५॥
15. When the first Navamsa of Mesha is rising, the letter
is क ; for Karkataka, the 4th, य ; for Tula, the 7th, च ; for
Makara, the 10th, प ; similarly for the second Navamsas of these
four, the letters indicated are in order छ, अ, ख and फ.
[It has been explained above that the letters are to be deduced
from the Navamsas of the 1st, 4th, 7th and 10th houses according
to their being owned by the several planets. Now when Mesha
happens to be rising, the first Navamsas of this and the other
Kendras are respectively Mesha, Kataka, Tula and Makara. These
are owned by Mars, the Moon, Venus and Saturn respectively.
Since they are the first Navamsas, we have to take the first letters
of the classes belonging to the planets, viz. क, य, च and प. When
the second Navamsas of Mesha, Kataka, etc are rising, the letters
will be for the same reason the second letters of the respective
classes, according to their ownership; e.g. in Mesha, the 2nd
Navamsa belongs to Venus, so the second letter of चवर्ग i.e., छ and
so on.]
मेषे टकारो हिबुके ठकारस्तुले तकारो मकरे थकारः ।
मेषे तु रेफो हिबुके जकारस्तुले बकारो मकरे गकारः ॥ १६॥
16. When the 3rd Navamsa of Mesha is rising, the letter
for it is ट; for the fourth house Karkataka, it is ठ; for the seventh
Tula, त; for Makara, it is थ; for the 4th Navamsa of Mesha,
Kataka, Tula and Makara, they are respectively र, ज, ब and ग.
[Though the Navamsa is the 3rd, still the letter taken, is the
first of the class ट, it is the first time that Mercury gets his chance.]
