Basic Chart (D-1) (Rasi Chart)
The basic birth chart of a native which is also called the Rashi chart is the 1st divisional chart termed as D-1. This chart is seen to ascertain everything about the body, constitution and health of native. This is the foremost chart for predicting future and is complete in itself. All other divisional charts only supplement and can never supplant the birth chart. The detailed method of its casting has been dealt with.
This chart is studied for wealth and prosperity of the native. Each sign of 30o is divided into two parts called horas of 15º each. The Sun and the Moon are allotted the lordship of these two divisions or horas. In odd signs the Sun rules the 1st half and Moon rules the 2nd half.In even signs Moon rules the 1st half and the Sun rules the 2nd half.
In other words, planets/lagna posited in the odd signs in the 1st hora i.e. 0º-15º are allotted to Leo and those in the 2nd hora i.e. 15º-30º are allotted Cancer. Similarly planets/lagna in even signs in 1st hora i.e. 0º-15º are allotted to Cancer and those in 2nd hora i.e. 15º-30º are allotted to Leo.
Maharishi Parashara in his Brihat Parashar Hora Shastra reveals some techniques of analyzing the hora chart. It says that Jupiter, Sun and Mars are good in Sun’s hora whereas Moon, Venus and Saturn are good in Moon’s hora. Mercury is good in both horas. In an odd sign Sun’s hora is powerful whereas in an even sign Moons hora is powerful. There is another viewpoint too. Benefic planets are considered good in even signs and in the hora of the Moon, where as malefics give good results in odd signs and in the hora of Sun.
II method :
If a planet/lagna is in 1st hora in D1, it will be in the same sign in D2. If a planet is in 2nd hora in D1, it will be in the 11th sign in D2, from its place in D1. In this method all the planets will be distributed in signs and hence the chart can be analyzed as if it is a Rasi chart. The position of 2nd lord, 11th lord of D1 and Jupiter are seen in D2.
