Chapter 6: The Muhūrta

The karaṇas, when avoiding Gara, Vaṇij, and Viṣṭi, are desired for one setting out on an expedition.

Even Gara is praised by some, and Vaṇij only in commercial activities.

Born of Śiva, Bhujaga, Mitra, Pitṛs, Vasus, Jala, Viśve[devāḥ], Viriñci, and Paṅkajaprabhava,

and whose sources are Indrāgnī, Indra, Niśācara, Varuṇa, and Aryaman—these are during the day;

Rudra, Aja, Ahirbudhnya, Pūṣan, the two Dasras, Antaka, Agni, and Dhātṛ,

and those named after Indu, Aditi, Guru, Hari, Ravi, Tvaṣṭṛ, and Anila—these are the muhūrtas at night.

Thus one fifteenth part of the day, and also of the night, receives the name muhūrta.

And that is to be determined by the knowledgeable through proper method by shadows, instruments, and water.

The parigha and other [yogas] of the muhūrtas should be considered alongside their presiding lords, just as with the lunar mansions.

The very same fruit has been seen by Garga and others; and on this subject there are verses:

"A complete day-and-night is joined with the lunar mansion of the moon;

and the muhūrtas of that lunar mansion are remembered to have identical actions and qualities."

The eighth, at exact midday, is auspicious; that muhūrta is named Viriñcivibhu.

Marching under that [muhūrta], known as Abhijit, is praised in all quarters except the south.
