Navamsa is the 1/9th division of a sign, equal to 3 degrees 20 minutes. The zodiac is divided into 108 parts, counting from the cardinal signs of each element - Aries, Capricorn, Libra, and Cancer. A planet is considered very strong and auspicious if it occupies the same sign in the natal and navamsa charts, known as being vargottama. To determine salary potential, one looks at the 2nd house for liquid assets and self-acquisition, the 6th house for service and remuneration, and the 10th house for profession, occupation, and employers.
