In January 1908 Sri Aurobindo had his first major spiritual experience, which he sometimes referred to as his Nirvana’ experience. To mark the Centenary of this event, which was celebrated by all the centres in Gujarat, Shraddhavan gave a talk at Savitri Bhavan, Auroville, on 7 January, 2008,sharing some of Sri Aurobindo’s statements about his experience, and connecting them with some remarks of the Mother about Thought Control and some passages in Savitri. Since Sri Aurobindo stated “One cannot be a fully developed mental being if one has not a control of the thoughts … these words have a practical application for all of us. Here is the audio recording of the talk.
