73. LONGEVITY FROM ASHTAKAVARGA

अथात्रायुः प्रवक्ष्येऽहमष्टवर्गसमुद्भवम् ।
दिनद्वयं विरेखायां रेखायां सार्धवासरम् ॥ १ ॥

दिनमेकं द्विरेखायां त्रिरेखायां दिनार्धकम् ।
वेदतुल्यासु रेखासु सार्धसप्तदिनं स्मृतम् ॥ २ ॥

द्विवर्षं पञ्चरेखासु षड्खासु चतुःसमा ।
षड्वर्षं सप्तरेखासु वसवोऽष्टासु वत्सराः ॥ ३ ॥

एवं यदागतायुः स्यात् सर्वखेटसमुद्भवम् ।
तदर्धं स्फुटमायुः स्यादष्टवर्गभवं नृणाम् ॥ ४ ॥

1-4: The Sage Parasara said Now, I will explain the procedure of fixing the longevity through the use of Ashtakavarga (system). The Ashtakavarga's Ayu has been fixed as the sign bearing 'no' Rekha will get two days; sign with one Rekha is assigned one and a half days; with four Rekhas - seven and a half days; with five Rekhas - two years; with six Rekhas - four years; with seven Rekhas six years and the eight Rekhas will attribute 8 years of Ayu. In this manner, study the number of the Rekhas in all the signs of the Ashtakavargas of all the planets and total up the Ayu contributed by them. Half the sum will denote Ashtakavarga's Ayu (longevity).
