Jean Klein's teachings on enlightenment are rooted in the Advaita Vedanta tradition, which emphasizes the non-dual nature of reality. He believed that true enlightenment is not a state to be achieved, but rather a recognition of our inherent nature as pure consciousness.

Klein taught that the mind is the main obstacle to experiencing this pure consciousness. The mind creates a sense of separation and duality, causing us to identify with our thoughts, emotions, and external experiences. This identification leads to suffering and a constant search for fulfillment outside of ourselves.

To overcome this limited perception, Klein emphasized the practice of self-inquiry. This involves questioning our beliefs and perceptions and recognizing that they are not our true self. By observing our thoughts and emotions without judgment, we can begin to detach from them and ultimately realize our true nature as pure consciousness.

Klein also emphasized the importance of being present in the here and now. He believed that true enlightenment is not a future goal, but something that can be experienced in each moment. By fully immersing ourselves in the present moment, we can let go of the past and future and connect with our true self.

In addition, Klein taught that the body and mind are instruments of consciousness, and we should not identify with them as our true self. This detachment allows us to experience a sense of freedom and peace, regardless of external circumstances.

Klein also emphasized the importance of silence and stillness in the path to enlightenment. By quieting the mind and letting go of the constant chatter, we can open ourselves up to experiencing the pure consciousness within.

Overall, Jean Klein's teachings on enlightenment revolve around the idea of letting go of the mind and ego to connect with our true nature as pure consciousness. By questioning our beliefs, being present, detaching from the body and mind, and finding stillness within, we can experience a deep sense of peace and fulfillment that is not dependent on external factors.
