Poojya Swamiji speaks about the importance of ‘thinking’ or ‘Introspection’ for a seeker. Repeated thinking over a concept is a great Sadhana which has a direct impact on the mind. Whenever you come across a concept, you keep revolving it in your mind until you become that.
Swamiji stresses on the fact that a seeker misses the Truth only because he does not take well to the Sadhana of introspection. ‘Repeated thinking’ itself is Sadhana.
