Self-Inquiry (Atma Vichara) is the central teaching of Ramana Maharshi. Rather than seeking truth through beliefs, rituals, or intellectual study alone, he encouraged individuals to turn their attention inward and investigate the source of the self. By repeatedly asking the question, "Who am I?", one begins to look beyond thoughts, emotions, and personal identity to discover the deeper awareness that underlies all experience. Ramana taught that the sense of a separate ego is the root of suffering and that true peace arises when one recognizes their essential nature as pure consciousness. Self-inquiry is not an intellectual exercise but a direct practice of inner observation. As attention returns again and again to the source of the "I" thought, the mind becomes quiet, revealing the ever-present Self that exists beyond the changing conditions of life. Through this process, one may experience greater clarity, freedom, and a profound sense of inner peace.
