In his autobiographical notes, Aurobindo said he felt a vast sense of calmness when he first came back to India. He could not explain this and continued to have various such experiences from time to time. He knew nothing of yoga at that time and started his practise of it without a teacher, except for some rules that he learned from Ganganath, a friend who was a disciple of Brahmananda .  In 1907, Barin introduced Aurobindo to Vishnu Bhaskar Lele , a Maharashtrian yogi. Aurobindo was influenced by the guidance he got from the yogi, who had instructed Aurobindo to depend on an inner guide and any kind of external guru or guidance would not be required.
