Sri Nisargadatta Maharaj was an Indian spiritual teacher and philosopher of Advaita (Nondualism), and a Guru, belonging to the Navnath Sampradaya. Sri Nisargadatta, with his direct and minimalistic explanation of non-dualism, is considered the most famous teacher of Advaita since Ramana Maharshi. In 1973, the publication of his most famous and widely-translated book, "I AM THAT", an English translation of his talks in Marathi by Maurice Frydman, brought him worldwide recognition and followers.

Oneness nonduality is a philosophical or spiritual concept that suggests that all things are interconnected and ultimately part of the same whole. It emphasizes the idea that there is no fundamental separation between individuals, objects, or experiences. This perspective promotes a sense of unity, interconnectedness, and a deeper understanding of the nature of reality.
