Jean Klein was a renowned Advaita master who brought a unique perspective to the ancient teachings of non-duality. He was known for his simple and direct approach, emphasizing the importance of self-inquiry and direct experience over intellectual understanding. Here are some key teachings of Jean Klein:

1. The true nature of self: According to Jean Klein, our true nature is not limited to the body-mind complex, but is the pure consciousness that underlies all experiences. This consciousness is always present, and can be realized through self-inquiry and letting go of identification with thoughts and sensations.

2. The illusion of separation: Klein taught that the sense of separation between the individual and the world is a false belief created by the mind. In reality, there is no separation between the self and the world, as everything is part of the same consciousness.

3. The importance of silence: Klein emphasized the power of silence in discovering our true nature. He encouraged his students to spend time in silence, observing the mind and allowing thoughts to pass without attaching to them. In this way, one can access the deeper stillness within.

4. Letting go of the ego: The ego, or the sense of individual identity, is a construct of the mind that creates suffering and separation. Klein taught that by letting go of the ego and its desires, one can experience a state of pure being and freedom.

5. The role of the body: While many spiritual teachings view the body as an obstacle to enlightenment, Klein saw it as a vehicle for experiencing consciousness. He emphasized the importance of being present in the body and using it as a tool for self-inquiry.

6. The power of direct experience: Rather than relying on intellectual understanding, Klein stressed the importance of direct experience in realizing our true nature. He encouraged his students to let go of concepts and beliefs, and instead focus on their own direct experience.

7. The unity of all religions: Klein saw the fundamental teachings of all religions as pointing to the same truth - the oneness of all things. He encouraged his students to look beyond the external forms of religious practices and connect with the essence of all spiritual teachings.

In summary, Jean Klein's teachings revolve around the idea of non-duality and the realization of our true nature as pure consciousness. He emphasized the importance of silence, self-inquiry, and direct experience in this journey, while also recognizing the unity of all religions. His teachings continue to inspire many seekers on the path of self-discovery.
