दशाफलाध्यायः
कृत्तिकादिस्त्रिरावृत्त्या दशा विंशोत्तरी मता ।अष्टोत्तरी न संग्राह्या मारकार्थं विचक्षणैः ॥ २ ॥
The Vimshottari period system is held to start from Krittika. The nine lords go round the stars three times. The wise should not use the Ashtottari system to find the periods that may bring death.
Simple meaning: 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.
उद्वेगिता हृदि ततो परितो लताव
The Sun's period tends to bring worry, quarrels with kin over property, loss of wealth and illness.
