“Buddha is someone with a very advanced self-concept. His self-esteem is perfect; he has gone beyond doubt; he knows, and he is confident of his knowledge; he expresses himself with conviction. When the Buddha talks of himself in the first person he does so with clarity. He has a strong sense of identity and knows very well who he is. He gives accounts of his life experiences in the first person.”
