युद्धजयार्णवः (योगाः नक्षत्राणि)
षष्ठी च गुरुणा दग्धा द्वितीया भृगुणा तथा ।सप्तमी सूर्यपुत्रेण त्रिपुष्करमथो वदे ॥ २३ ॥
In the full Agni Purana this is chapter 126, verse 23.
The 6th is burnt by Jupiter, the 2nd by Venus, and the 7th by Saturn, the Sun's son. Now I tell the Tripushkara.
Simple meaning: Jupiter burns the 6th, Venus the 2nd and Saturn the 7th. A combination that triples results comes next.
द्वितीया द्वादशी चैव सप्तमी वै तृतीयया ।
The 2nd, 7th and 12th moon days, with Sunday, Tuesday or Saturday, make Tripushkara, a three-fold result.
विशाखा कृत्तिका चैव उत्तरे द्वे पुनर्वसुः ।
Six nakshatras make Tripushkara: Vishakha, Krittika, two Uttaras, Punarvasu and Purva Bhadrapada.
लाभो हानिर्जयो वृद्धिः पुत्रजन्म तथैव च ।
In that combination, gains, losses, wins and a son's birth all come three times over.
