Hindus believe in putting a different face on a form of God. In Hinduism, Various forms of God are given a particular day for reverence. Also, a follower or a devotee can appease to certain dosh in his stars through diligent puja and devotion to God on particular days.

The fasting on Mondays in the Shravan month is considered even more auspicious.

Any Upvaas or Vrat is directly or indirectly connected with some sort of material comfort. This is a sweet lure used by ancient saints to attract a devotee to the concept of Brahman. The concept of Brahman in Sanatana Dharma is not easily digestible to many people. And they are least bothered about Brahman concept all they need is material comfort. For this many devotees are ready to go to any extent. They are ready to observe any harsh vow. Ancient wise men used this tendency among the common people to spread the awareness of Brahman. During each upvas, there are occasional flashes when a person thinks beyond material comforts. This is a realization of Brahman. Gradually many devotees begin to think beyond material comforts
