Pranayama is the basic and a must. Some breathing awareness, some sanskrit sounds and some Gods names are there in Pranayama.
Everything else depends on what you take from it. It can be as simple as a song to as detailed as a DETAILED SINCERE APOLOGY AND PURIFICATION AND RESPECT TO YOUR FOREFATHERS.
PS: on the Comedy side, a simple sastrigal told me u dont have to travel from mars to jupiter and their anologies to athma, pramathma etc.
Since your question is an open ended one, i chipped in. LOL
