Trimśāṁśa

What is the Trimsamsa, and how to draw a Trimsamsa Chart?

Trimsamsa means the one-thirtieth portion of a sign measuring one degree. Unlike other divisions, the Sun and Moon are not the Lords of any trimsamsa and the Nodes (Rahu & Ketu) also do not owm any trimsamsa. Thus the remaining five of Mars, Mercury, Jupiter, Venus and Saturn own the trimsamsa. They represent the five elemental states of existence (see table 1).

Table 1: Five Elements

Table 2: TRIMSAMSA

The positions of the planets and the Lagna in the Rasi chart are used to determine the Trimsamsa occupied by them. For example, if Jupiter is in 26-07′ in Pisces, then since it is in an even sign, from Table 2, we see that it is in Scorpio (even sign ruled by Mars). In this manner, the trimsamsa of all the planets and Lagna is determined and the resultant chart is called the Trimsamsa or D-30 Chart. The trimsamsa chart of the standard nativity is given below.

A chart which is constructed like a dvadasamsa but is a shastiamsa shows the genetic makeup of the individual and biological problems because when it is like d12 or d60 chart, it shows the dosha coming from creation. Then this is called a d30S chart where S stands for Shastyamsa like Trimsamsa. But we can also call it d30V diving credit to the author who published this in the Jataka Parijata.
