कृत्तिकादिस्त्रिरावृत्त्या दशा विंशोत्तरी मता ।
The Vimshottari system starts from Krittika. Do not use the Ashtottari system to find periods that may bring death.
गतर्क्ष नाडीनिहता दशाब्दै
Multiply the passed part by the period's years. Divide by the full length. The rest is still to come.
दशा दशाहता कार्या विहृता परमायुषा ।
Multiply period by period and divide by 120 years. This gives the sub-periods. The sub-sub-periods use the same ratio.
