Purshottam / Adhik Maas
Adhik - Extra
Maas - Month
Purshottam - Supreme Lord
The Hindu calendar is based on the lunar cycle rather than the solar cycle. Due to this, an extra month arises after every thirty two month period. During this month additional Religious duties are performed as prescribed in the Shikshapatri (Slokha 77-78) e.g. pradikshina, mala, listening to katha etc. Satsangi's also give gifts to the Lord and alms to Brahmins and the poor according to their ability.
This month is regarded as very auspicious and great Punya is attached to it, so it is very important that we do not waste this opportunity to serve Lord Swaminarayan to the best of our ability.
