In Garuda Purana, Vishnu reveals to Siva, Yogas & Muhurtas, good or bad lunar and week days as per Vedic Astrology when travel should be avoided or undertaken for better prospects.
Lord Vishnu told Shiva : ‘Various Yoginis (goddesses) dwell in different directions on specific lunar days and one should never set out for long journeys on those days.
A yogini named Brahmani dwells in the East on Pratipada(first) and navami(ninth) of both the fortnights of each month and nobody should travel on both these dates towards east.
Maheswari dwells in the north on second and ninth of both the fortnights of each month, so nobody should travel towards north on both these dates.
Varahi dwells in the south on the fifth and thirteenth of both the fortnights of each month and hence it is unadvisable to travel towards south on the those lunar dates.
Indrani dwells in the west on sixth and fourteenth of both the fortnights of each month and therefore nobody should travel in this direction on both the above mentioned dates.’
While giving names of some auspicious Nakshatras suitable for undertaking journeys, lord Vishnu said : ‘Constellations like Aswini, Anuradha, Revati, Mrigasira, Moola, Punarvasu, Pushyami, Hasta and Jyeshta are auspicious for undertaking journeys.‘
Lord Vishnu, while revealing some specific combinations of days and tithis (lunar days) considered to be inauspicious, said : ‘ One should never travel on the following inauspicious days: Dwadasi falling on Sunday or Ekadasi falling on Monday or Navami falling on Wednesday or Ashtami falling on Thursday or Saptami falling on Friday and Shashti falling on Saturday.‘
