ज्योतिःशास्त्रम्
मिथुनस्थे रवौ दर्शाद्यदि स्याद्द्वादशी तिथिः ।सदा तत्रैव कर्तव्यं शयनं चक्रपाणिनः(?) ॥ ५५ ॥
In the full Agni Purana this is chapter 121, verse 55.
With the Sun in Gemini, say the 12th tithi (moon day) comes after the new moon. Then the sleep of Chakrapani (Vishnu) is always kept there. (Our text is unclear here: the print marks the word Chakrapani with a question mark.)
Simple meaning: Vishnu's sleep rite falls on the 12th moon day after the new moon, with the Sun in Gemini.
सिंहतौलिगते चार्के दर्शाद्यद्वादशीद्वयम् ।
With the Sun in Leo and Libra, the two 12th days are for Indra's raising and Hari's waking.
तथा कन्यागते भानौ दुर्गोत्थाने तथाऽष्टमी ।
Durga's raising falls on the 8th with the Sun in Virgo. A special case follows.
भौमादित्यशनैश्चारी(?) विज्ञेयं तत्रिपुष्करम् ।
This mix on Tuesday, Sunday or Saturday is Tripushkara. Check the Moon and the star count for all work.
