Thiru Maraikadu (Vedaranyam) Temple, TN. |
Regarding Ardhodaya Punyakalam and Mahodaya Punyakalam, it is stated as follows in the compendium of Dharma Sastra 'Smriti Muktaphalam' in 'Sradha Kandam-Uttara bhaga':
महाभारते श्रवणाश्विधनिष्ठार्द्रानागदैवतमापतेत्।
रविवारयुतामायां व्यतीपातः स उच्यते॥
व्यतीपाताख्ययोगोऽयं शतार्कग्रहसन्निभः॥
If on a Sunday, Amavasya and one of the stars – Sravanam, Asvini, Avittam, Thiruvadirai or Ayilyam, occurs, then it is called 'Vyatipatam'. This Vyatipata yogam is equal to a hundred Surya grahanas in merit.
