What benefits accrue from Maun-vrat?
Maun-vrat literally means a vow to keep silent. For spiritual growth it is essential that one's speech must be pure. To acquire purity of speech the practice of silence is important. Hindu religious texts commend maun-vrat for this purpose. In Bhadon, the sixth month of the Hindu calendar, 16 days of maun-vrat are said to be useful. It is believed that through silence one is able to achieve one's desires. One attains the abode of Lord Shiva. Along with maun-vrat it is essential that some time must be spent in offering prayers.
In the Bhagavad Gita, 17/16, it is said:
Contentment of the mind, amiable temperament, silence, religious meditation and good thoughts reflect austerity of the mind.
Silence is placed mid-way between other qualities. It begins with control of the mind. Once the mind is controlled, one becomes friendly. One begins to look kindly towards others. One cuts down on useless speech and thinks more of God. One begins to generate good thoughts.
