Now I will tell you the method of working out the Antardasas in the Pinda, Amsa and Nisarga Dasas. The lord of Dasa is Dasa Pachaka of full part (1) of the planet associated with, is pachaka of 1/2 part the planet in trikona from him, is pachaka of 1/3 part and the planet in the 4th and 8th from him are pachaka of 1/4 part and the planet in the 7th from him is pachaka of 1/7 part of the Dasa. No planet in any other house is Antardasa pachaka. In this manner there are Antardasa pachakas in the above mentioned houses from the various houses including the Ascendant. In any of such houses if there be more than one planet, then the one who is the strongest amongst them will be the pachaka. Take the fractions (as mentioned above) and reduce them equivalent fractions with a common denominator. Add up the aliquot parts of the Dasa representative of the various numerators leaving out the denominators. The Antardasas will be arrived at when the various aliquots are converted into years, months etc. within the main Dasa and divided by a common factor.
