Auspicious means the dissolver of sin and giver of excellent happiness.
Purest feelings of soul is the best bliss. Auspiciousness of region, place and time cannot be fully meaningful without it.
Even the crematorium is a worthy place for meditation for a person with a pure mind. But person with spiteful and cruel feelings
can be hostage to inauspicious karmas even in a temple or near Parmeshthi. Any day of the week or fasting days cannot be auspicious without making your feelings pure and auspicious. A sword named chandrahaas was auspicious for Laxman and became inauspicious for Shambuk.
True God, scriptures and Guru (preceptor) are auspicious but only then when you become worthy of receiving welfare.
