Personality

Ramanujan has been described as a person with a somewhat shy and quiet disposition, a dignified bearing and pleasant manner. He was also known to be extremely sensitive. On one occasion, he had prepared a buffet for a number of guests, and when one guest politely refused to taste a dish he had prepared, he left immediately and took a taxi to Oxford. He also lived a rather spartan life while at Cambridge. He frequently cooked vegetables alone in his room.
 

Spiritual Life

Ramanujan believed in Hindu gods all his life and lived as an observant Tamil Brahmin. "Iyengar" refers to a class of brahmins in southern India who worship the god Vishnu, the preserver of the universe. His first Indian biographers describe him as rigorously orthodox. Ramanujan credited his acumen to his family goddess, Namagiri, and looked to her for inspiration in his work. He often said, "An equation for me has no meaning, unless it represents a thought of God."
