Phaladeepika
वाक्येषु यावच्छरदां प्रमाणं वदन्ति तावत्परमायुरत्र । मेषादनीकं मदनं गजेन तुन्दः पुनश्चैवमुदीरितं तत् ॥ १४॥
The total number of years indicated by the sum of the nine mnemonical syllables of any formula represents the number (in years) of Parama Ayus for that formula. Thus, the Parama Ayus in years for the 12 Rasiamsas reckoned from Mesha in an Apasavya Chakra will be 100, 85, 83 and 86 repeated thrice, while those for the 12 Rasiamsas reckoned from Vrischika in a Savya Chakra will be the same but in the reverse order ; that is, 86, 83, 85 and 100 repeated thrice.
