Ch. I – Miśrakādhyāyaḥ 9 20 Prathamā, Dvitīyā, Ṣaṣṭhī is auspicious in the Sun, as are Aṣṭamī, Prathamā, Pañcamī, in the Moon. Caturthī (Veda), Saptamī, Aṣṭamī are auspicious in Maṅgala (Bhauma) and Aṣṭamī, Tṛtīyā and Ṣaṣṭhī (Rasa) are auspicious in Budha. 21. Dvitīyā, Pañcamī, Saptamī in Bṛhaspati, Aṣṭamī, Prathamā, Ṣaṣṭhī, Saptamī (Abdhi) in Śukra and Tṛtīyā, Pañcamī, Saptamī and Aṣṭamī in Saturn and the 8th part of the day; these all are regarded as auspicious. 22. In all sorts of constructions, the learned men prefer the strength of lunar zodiac, because it has a hundred times more strength and without the influence of the moon, no work can be done. 23. Daśamī, Ekādaśī, Ṣaṣṭhī, Tṛtīyā, Prathamā, Saptamī, in both the Pakṣa (bright and dark fortnights) of the moon are said to be beneficial, and for the bright fortnight (śukla), Pañcamī, Navamī, Dvitīyā (are beneficial). 24. In the dark fortnight after Daśamī the power of the moon decreases for the next ten days but, in conjunction with favourable stars, the same yields good result except in Tṛtīyā, Pañcamī and Saptamī. 25. The twelfth position of the moon in the twelve zodiac signs yields results according to the respective positions like Pravāsa etc, in the Meṣa and others, serially in each zodiac sign. 26. They are Pravāsa, Nāśinī, Mṛtyu, Jayā, Hāsyā, Rati, Krīḍitā, Nidritā, Bhuktā, Jvaritā, Kampitā, Sthitā.
