Narada Purana — Purva Bhaga, Shloka 21
Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
घनं च विषमादेवं घनमूलं मुर्हुभवेत् । अन्योन्यहारनिहतौ हरांशौ तु समुच्छिदा ॥ २१ ॥
ghanaṃ ca viṣamādevaṃ ghanamūlaṃ murhubhavet | anyonyahāranihatau harāṃśau tu samucchidā || 21 ||
