In yoga, the realization of the higher Self is part of spiritual liberation (or moksha). This realization can be acquired through spiritual practice and discipline. The higher Self is the part of an individual that connects with the Divine (or a higher power or energy, depending on specific beliefs of an individual).
The higher Self is a state of consciousness that can be accessed through meditation and introspection, which promote greater self-awareness and acceptance. Yoga philosophy views each person's core self as perfect, but aims to help bring awareness to negative patterns or thoughts that may not be serving a person's higher purpose. The opposite of the higher Self is the ego, which centers on more worldly attachment and self-centered needs.
