Self-inquiry is a central aspect of Mooji's teaching and is often referred to as the "direct path" to self-realization. It is a practice that involves questioning the nature of one's own existence and ultimately leads to the understanding of one's true self.

Mooji emphasizes the importance of self-inquiry as it allows individuals to go beyond the limitations of the mind and ego, and discover their true essence. He encourages his students to question their thoughts, beliefs, and perceptions, and to investigate the source of their suffering and limitations.

According to Mooji, the mind is the main obstacle to self-realization as it creates a false sense of identity and separation from the true self. Through self-inquiry, one can become aware of the mind's tricks and illusions, and eventually transcend it.

Mooji's approach to self-inquiry is simple yet powerful. He encourages individuals to ask the question "Who am I?" and to observe the thoughts and sensations that arise in response. By questioning the "I" or the sense of self, one can realize that it is just a concept created by the mind and not the true self.

He also guides his students to focus on the awareness behind the thoughts, rather than getting caught up in the content of the thoughts themselves. This allows individuals to experience a state of pure awareness, free from the limitations of the mind.

In Mooji's teaching, self-inquiry is not just an intellectual exercise, but a direct experience of one's true nature. He often uses the metaphor of a mirror to explain this concept – just as a mirror reflects whatever is placed in front of it without any judgment or attachment, the true self is pure awareness that reflects everything without any identification.

Through self-inquiry, Mooji's students are able to let go of their false identities and realize their true nature as pure consciousness. This leads to a profound inner peace and a sense of freedom from the limitations of the mind.

In conclusion, self-inquiry is an essential aspect of Mooji's teaching as it allows individuals to directly experience their true self and transcend the limitations of the mind. By questioning the sense of self and focusing on pure awareness, one can ultimately realize their true nature and live in a state of peace and freedom.
