Tikkanikayatra 3: chap.3.muhūrtakarmaguṇa

The half lunar days, with Gara, Vaṇij, and Viṣṭi excluded, are desired for the expedition leader; / Gara too is commended by some, and Vaṇij only in mercantile activities.

During the day [the auspicious moments are those presided over by] Śiva, Bhujaga, Mitra, the Pitṛs, the Vasus, Jala, the Viśvedevas, Viriñci, the Lotus-born [Brahmā], / Indra-Agni, Indra, the Night-wanderer, Varuṇa, and Aryaman as their sources.

By night the auspicious moments are named after Rudra, Aja-Ekapād, Ahirbudhnya, Pūṣan, Dakṣa, the Ender [Yama], Agni, Dhātṛ, / the Moon, Aditi, Guru, Hari, the Sun, Tvaṣṭṛ, and Anila.

The fifteenth part of the day and likewise of the night is designated a muhūrta; / and that is to be ascertained by those skilled in it through reason, with shadows, instruments, and water-clocks.

The parigha line and so forth of the auspicious moments should be considered like the lunar mansions, along with their presiding lords; / the fruit seen by Garga and others is indeed the same, and there are verses on that subject:

"A complete day-and-night is joined to the Moon's lunar mansion; / and the muhūrtas of that lunar mansion are recorded as possessing equal actions and virtues."

And that which is the eighth muhūrta, named after Viriñci, is designated as Abhijit; / during that [time] […] for one who has advanced far to the south, there is attainment of victory.

The [auspicious moment] named after the lord Viriñci, which is auspicious when equal to the eighth [part] in the daytime— / by that, setting out is commended in all directions under Abhijit, setting aside the south.
