Throughout his life, Klein continued to deepen his understanding of Advaita and share it with others. He had a gentle and compassionate teaching style, and his presence was said to have a calming effect on those around him. He was highly respected and revered by his students, who saw him as a living embodiment of the Advaita teachings.

In summary, Jean Klein became an Advaita master through a combination of personal experiences, spiritual practices, and guidance from his own teachers. His dedication to Advaita philosophy and his unique approach to teaching have left a lasting impact on the spiritual community, and his teachings continue to inspire and guide seekers on the path of self-discovery.
