The phrase "neti neti" holds great significance in the teachings of Nisargadatta Maharaj, the Indian spiritual teacher and author of the popular book "I Am That." This phrase, which translates to "not this, not this" in English, is a powerful tool for self-inquiry and realization.

In Maharaj's teachings, the phrase "neti neti" is used as a way to guide individuals towards understanding the true nature of the self. It is a reminder to look beyond the external world and the labels and identities we attach to ourselves, and instead focus on the pure awareness that exists within us.

Maharaj believed that our true self is not limited by any concepts or descriptions, and can only be understood through the process of negation. By negating all that is not our true self, we can come to a deeper understanding of our true nature.

The concept of "neti neti" is rooted in the ancient Indian philosophy of Advaita Vedanta, which Maharaj studied and taught. According to this philosophy, the ultimate reality is non-dual and beyond all concepts and descriptions. In order to realize this truth, one must go beyond the mind and its limitations, which can only be achieved through the process of negation.

Maharaj often used the analogy of a screen to explain the concept of "neti neti." Just as a screen allows different images to be projected onto it, but remains unchanged and unaffected by them, our true self is like a screen that allows the experiences of life to pass through it, but remains untouched by them.

By using the phrase "neti neti," Maharaj encourages individuals to let go of all concepts and ideas about themselves and the world, and instead focus on the pure awareness that exists within. This can lead to a profound realization of the true self, which is beyond all limitations and definitions.

In conclusion, the phrase "neti neti" is a powerful tool in Nisargadatta Maharaj's teachings, reminding us to look beyond the external world and our limited identities, and instead focus on the pure awareness that is our true nature. It is a reminder to let go of all that is not our true self, and to ultimately realize the non-dual nature of reality.
