84. Maharishi Parashar said. 5, 21, 7, 9, 10, 16 and 4 years are the Dasha spans of Surya, Candr, Mangal, Budh, Guru, Sukr and Sani.

85-86. The span of life of a person is determined from the Padas (Ansas) of the Nakshatr at the time of birth, or the time of query and the years allotted to the 9 Rasis, commencing from it (the Pad of the Nakshatr). Some sages are of the view, that the person will enjoy full span of life (Purna Ayu), if his birth is at the commencement of the Padas, will have middle span of life (Madhaya Ayu), if the birth is in the middle of the Padas and short span of life (‘Alap Ayu’), or will face death-like sufferings, if the birth is at the end of the Padas of the Nakshatr.

87-88. According to this principle, we should be acquainted with the Padas of the Nakshatras. Now I shall tell you, how the calculations are made, according to the proportion of the Padas of a Nakshatr. The number of Ashvini etc., whichever may be the past Nakshatras, should be divided by 3. Thereafter the remainder should be multiplied by 4. To the figure so made available the Pad of the present Nakshatr should be added. The product will be the Navans from Mesh onwards.

89. The number of years (Purna Ayu) are, as under. For the Ans in Mesh 100 years, in Vrishabh 85 years, in Mithun 83 years, in Kark 86 years. The number of years will be the same for Rasis, situated the 5^th and 9^th to them.
