Nadyamsa from Parasara's shodasa vargas (shastyamsa)

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.
