விம்சோத்தரி தசையில் கிரகங்கள் மற்றும் ராசியின் புக்தியின் வேலைகள். - பிருஹத் பராசர ஹோர சாஸ்திரம்

13-16. Now I will tell you the method of working out the Antar Dashas in the Pinda, Ans and Nisarg Dashas. The Lord of Dasha is Dasha Pachak of full part, the Grah, associated with, is Pachak of ½ part, the Grah in Trikon from him is Pachak of l/3 part and the Grah in the 4^th and 8^th from him are Pachak of ¼ part, the Grah in the 7^th from him is Pachak of l/7 part of the Dasha. No Grah in any other Bhava is Antar Dash Pachak. In this manner there are Antar Dasha Pachakas in the above-mentioned Bhavas from the various Bhavas, including Lagn. In any of such Bhavas, if there are more than one Grah, then the one, who is the strongest amongst them will be the Pachak. Take the fractions and reduce them in equivalent fractions with a common denominator. Add up the aliquot parts of the Dasha, representative of the various numerators, leaving out the denominators. The Antar Dashas will be arrived at, when the various aliquots are converted into years, months etc. within the main Dasha and divided by the above sum. (The calculations, given above, are not the literal translation of the text in the verses concerned, but their actual meaning and sense. This has been got confirmed by checking up with similar information, given in Kalyana Varma’s Saravali and Varamihir’s Brihat Jatak)
