Self-Inquiry, also known as "Who am I?" is a powerful method of liberation taught by the renowned Indian sage, Ramana Maharshi. It is a process of introspection and self-examination that aims to uncover the true nature of the self and ultimately lead to liberation from the ego.

The concept of the ego is deeply intertwined with Self-Inquiry. The ego, or the sense of individual identity, is often seen as the root cause of suffering and the main obstacle to self-realization. It is the false sense of self that is created and sustained by our thoughts, beliefs, and attachments.

Self-Inquiry challenges the ego by questioning its very existence. By continuously asking "Who am I?", one begins to unravel the layers of conditioning and false identities that make up the ego. This process of self-investigation allows one to see through the illusion of the ego and recognize the true nature of the self.

As one delves deeper into the practice of Self-Inquiry, they begin to realize that the ego is not a solid and fixed entity, but rather a constantly changing and impermanent construct. This understanding helps to loosen the grip of the ego and allows one to break free from its limitations.

Moreover, Self-Inquiry also helps to cultivate a sense of detachment from the ego. By questioning its existence, one begins to distance themselves from the ego and its desires, attachments, and fears. This detachment allows for a deeper understanding and acceptance of the true self, which is beyond the ego.

Through Self-Inquiry, one can also come to the realization that the ego is not the true self. It is merely a collection of thoughts, emotions, and experiences that do not define the essence of who we are. This understanding helps to dissolve the ego and reveal the true self, which is pure consciousness and infinite in nature.

In conclusion, Self-Inquiry is a powerful tool for liberation from the ego. By continuously questioning the ego and cultivating detachment from it, one can uncover the true nature of the self and ultimately attain liberation. As Ramana Maharshi said, "The ego is like a phantom which appears in the darkness. Let the light of Self-Inquiry shine upon it and it will vanish."
