The spiritual seeker who desires to start abhyas (practice) has to take a minimum of three introductory sittings (meditation sessions) from a preceptor over a period of three days, consecutively. Each session will last about half-an-hour during which the preceptor directs the Master's transmission to the abhyasi's heart and cleans it of samaskaras. This brings about mental lightness and enables the abhyasi to meditate alone.
