What Is the Vimsamsa (D20) Chart?

Each sign divides into twenty equal 1°30′ parts. A movable sign’s division starts from Aries, a fixed sign’s from Sagittarius, and a dual sign’s from Leo — producing a chart specifically oriented toward inner and spiritual life rather than outer achievement.

Reading Spiritual Inclination From the D20

The D20 Lagna and its planetary occupants are read for the nature of a person’s spiritual practice, religious inclination, and capacity for devotion — whether that shows up as ritual observance, meditation, philosophical inquiry, or another form of inner-directed practice.

A Chart of Inner Life, Not Outer Success

Unlike the D10 (career) or D1 (general life), the D20 deliberately doesn’t speak to worldly achievement — a strong D20 doesn’t predict career success, and a weak one doesn’t predict career failure; it’s a separate axis entirely, concerned with the inner life.
