Spiritual significance of Mauni Amavasya
The basic element of Mauni Amavasya is religious and cultural conduct. It is believed that on this day the gods come to earth to reside in the holy rivers and confluences. That is why major pilgrimage sites, especially on the banks of the Ganga, see large crowds of devotees coming to bathe and pray.
The fast begins with a bath in the holy river or lake at sunrise. The most important aspect of this day is the “Maun Vrat” or “Vow of Silence”, whereby devotees control their senses and focus on introspection. It is said in the scriptures that praying in the mind on this day is considered more fruitful and powerful.
