Vyatipata Doshas

The 5 upagraphas : Dhooma, Vyatipata, Parivesha, Chap and Upaketu. These are not physical bodies but invisible points in the space and only reckoned by mathematical calculation and experienced by their effect. We will consider here calculation of the first two components only to make it clear that every person has vyatipata yoga placed in a house of the horoscope on the basis of difference between longitude of the Sun and the Moon.
First the upagraha Dhooma is to be calculated by adding 133 degrees and 20 minutes of arc to longitude of the Sun at a given moment.
Once longitude of Dhooma is calculated, Vyatipata can be reckoned by substracting Dhooma's longitude from 360 degrees.
