You are just at the right point. Those who read Sri Aurobindo and the Mother - their attitude to the world, India and the sacred books take a new turn. Sri Aurobindo and Ma came to build a future that is peeping through us. Only we must be aware of it.
The Gita, the Upanishads etc - however great these books are - they can not help the future Sri Aurobindo came to bring in. And the pertinent point is that we will miss the relevance of these books if they are not read in the light of Sri Aurobindo. Without Sri Aurobindo - these books will be serving the usual satisfaction that one can get through religion.
