Antar Mouna

The Sanskrit word mouna means 'silence', and antar means 'inner'. Therefore, the English name of this practice is 'inner silence' and it is a great sadhana designed to make the aspirant aware of the inner silence as well as the inner noise which generally prevents one from knowing the silence.
