Moksha, or liberation, is the ultimate goal of human existence in Vedanta philosophy. It is a state of freedom from all suffering and ignorance, and it is achieved through the realization of the true Self.

The true Self, or Atman, is considered to be separate from the body and mind in Vedanta philosophy. It is an eternal, unchanging, and infinite consciousness that is the essence of all beings.

The realization of the true Self is achieved through meditation and self-inquiry. Meditation helps to quiet the mind and focus on the inner Self, while self-inquiry helps to remove the obstacles that prevent the realization of the Self.

Brahman and Atman are considered to be identical in Vedanta philosophy. Brahman is the universal Self, while Atman is the individual Self. When the individual Self realizes its true nature, it merges with Brahman and becomes one with the universal consciousness.

Ignorance, or avidya, is considered to be the root cause of suffering in Vedanta philosophy. It is the ignorance of the true nature of the Self that leads to the experience of suffering.

Liberation, or moksha, is a state of freedom from suffering and ignorance, a state of eternal bliss and happiness, and a state of oneness with Brahman. It is the ultimate goal of human existence in Vedanta philosophy.
