The role of a teacher in Advaita, a non-dualistic philosophy of self-realization, is crucial in guiding and supporting individuals on their spiritual journey towards understanding their true nature. The teacher serves as a mirror, reflecting back to the student their own innate wisdom and helping them to remove any obstacles that may be hindering their understanding.

One of the main roles of a teacher in Advaita is to impart knowledge and understanding of the non-dual nature of reality. This is done through various means such as lectures, discussions, and one-on-one interactions. The teacher helps the student to see beyond the limitations of the mind and to recognize the underlying unity of all things.

Another important role of the teacher is to provide guidance and support to the student in their spiritual practices. This may include meditation, self-inquiry, and contemplation, which are all essential tools in the path of Advaita. The teacher helps the student to understand the purpose and importance of these practices and how to integrate them into their daily life.

In addition, the teacher also plays a crucial role in addressing any doubts or questions that may arise in the student's mind. Advaita emphasizes the importance of questioning and inquiry in order to gain a deeper understanding of the self. The teacher encourages the student to ask questions and provides clear and concise answers, helping to dispel any confusion or misunderstandings.

Furthermore, the teacher serves as a role model for the student, embodying the qualities of compassion, wisdom, and unconditional love. Through their own presence and example, the teacher inspires and guides the student towards a deeper understanding of their true nature.

It is important to note that the role of the teacher in Advaita is not one of authority or hierarchy. The teacher is seen as a friend and guide, rather than a superior or guru. The teacher and student are seen as equal in their true nature, and the teacher simply acts as a catalyst to help the student realize this truth within themselves.

In conclusion, the role of the teacher in Advaita is multi-faceted and essential in guiding individuals towards self-realization. Through imparting knowledge, providing guidance and support, addressing doubts and questions, and serving as a role model, the teacher plays a crucial role in the spiritual journey of the student.
