Peace

Those who do not have perfect peace will not get established in Samadhi even if they sit in Padmasana with their hands in special positions. Only self knowledge which is a fire for the straws of desires, is superb samadhi. Remaining still is not samadhi.

From Jnana Vasishtam

Self knowledge cannot be obtained from asana practice. Asanas can give a little knowledge about the body but this is highly limited. Even doctors dont understand the working of body with sophisticated lab tools.

Self knowledge can be secured only by deep introspection and rejecting what is false and the truth alone remains.
