Self-Inquiry, also known as "Who am I?" is a powerful method of liberation taught by the renowned sage Ramana Maharshi. It is a form of introspection that aims to help individuals realize their true nature and break free from the limitations of their mind.

One may wonder if this practice can be done without the guidance of a teacher. The answer is yes, but with certain caveats. Self-Inquiry can be practiced without a teacher, but it requires a deep understanding of the teachings and a strong commitment to the practice.

The first step in Self-Inquiry is to ask the question "Who am I?" and then to observe the mind for any thoughts or feelings that arise in response. The key is to not engage with these thoughts or try to analyze them, but simply to observe them without judgment. This requires a certain level of detachment and awareness, which can be challenging to achieve without the guidance of a teacher.

A teacher can provide the necessary support and guidance to help individuals navigate through their inner experiences and overcome any obstacles that may arise. They can also offer insights and perspectives that may not be apparent to someone practicing on their own.

Moreover, Self-Inquiry can bring up deep-seated emotions and traumas that may be difficult to handle alone. A teacher can provide a safe and supportive space for individuals to process and heal these emotions.

However, if one is unable to find a suitable teacher or does not have access to one, it is still possible to practice Self-Inquiry on their own. It is important to approach the practice with sincerity, patience, and an open mind. It may also be helpful to read and study the teachings of Ramana Maharshi and other spiritual masters to deepen one's understanding of the practice.

In conclusion, while Self-Inquiry can be practiced without a teacher, it is recommended to seek guidance and support from a teacher whenever possible. The journey of self-discovery and liberation can be challenging, and a teacher can provide valuable insights and support to help individuals navigate through it. However, with dedication and perseverance, one can still experience the profound benefits of Self-Inquiry on their own.
