Nadyamsa from Parasara's shodasa vargas (shastyamsa)

[Guest guest]

Dear Graham,

If I may add, this (unequal Nadi Amsha) is also the way suggested by

C.S. Patel, who is past 90 years now and did a lot of research on Nadi

Amsha.

Chandrashekhar.

That's partly true and partly inaccurate.

Parasara may not have mentioned nadyamsa. But nadyamsa, as I understand

it, is rooted in shodasa varga (16 divisions) taught by Parasara.

Some people divide each sign into 150 equal parts and call them the 150

nadyamsas.

But we use a different kinds of nadyamsa. Both the varieties are

available in the free software Jagannatha Hora 7.02.

In this variety (called "Chandra Kala Nadi" in the software), we mark

the boundaries of various vargas in rasis. For example, navamsa borders

are at 3 deg 20 min, 6 deg 40 min, 10 deg etc. Dasamsa borders are at 3

deg, 6 deg, 9 deg etc. Chaturvimsamsa borders are at 1 deg 15 min, 2

deg 30 min, 3 deg 45 min, 5 deg etc.

If we mark the boundaries within each sign based on all the sixteen

divisions and count how many distinct partitions are in the sign, we

will get exactly 150 portions! Some portions are smaller than 12

arc-min and some are bigger. But, there are exactly 150 unequal

portions as a result of dividing the rasi based on shodasa vargas.

Chandra kala means phases of Moon and means 16. So we call this

"Chandra Kala Nadi", i.e. nadi from 16 [vargas].

If you ask me, this is the correct nadyamsa and the one obtained from

uniform division of a sign into 150 equal parts is wrong. Thus,

nadyamsa is rooted in shodasa varga.

Each nadi is basically a unique combination of shodasa varga parts.

May Jupiter's light shine on us,

Narasimha
