Ganapati's Treatise on Auspicious Moments

Now, the portions to be avoided in the inauspicious Yogas:
One should avoid the entirety of the Yogas named Vaidhriti and Vyatipada for any auspicious activity. In Vajra and Vishkambha, avoid the first three ghatikas A ghatika is a unit of time equal to 24 minutes; three ghatikas equal 72 minutes. (4) Avoid the first half of Parigha; nine ghatikas in Shula and Vyaghata; and six ghatikas in Ganda and Atiganda. These are to be avoided in all rituals. (5) This is the general rule remembered for these Yogas. Some authorities, however, simply discard the first quarter of any inauspicious Yoga. (6)

(3) In the first half of the first day of the bright fortnight, the Karana is named Kimstughna. These four [Shakuni, Chatushpada, Naga, and Kimstughna] are known as the "Fixed" Karanas. (4)

Now, the Lords of the Karanas:
Indra, Brahma, Mitra, Aryaman, Bhumi (Earth), Shri (Lakshmi), Yama, Kali, the Sun, the Serpent (Naga), and Vayu (Wind) are the presiding deities of the Karanas. (5) In Bava, perform acts for nourishment and growth; in Balava, perform rituals related to Brahmins. In Kaulava, activities related to women and friends are favored; in Taitila, acts that are auspicious and dear.
