Swami Sivananda

Oneness of Self or oneness of Existence is Reality, and the realisation of this Reality is Moksha.

Moksha is the breaking down of the barriers that constitute separate existence. Moksha is the absolute state of Being, where the unity of all-pervading and all-permeating consciousness is realised with certainty, like that of an orange which we see in our palm.

Moksha is not an attainment of liberation from an actual state of bondage, but is the realisation of the liberation which already exists. It is freedom from the false notion of bondage.

The individual soul feels itself to be in bondage on account of ignorance caused by the power of Avidya. When the false belief caused by delusion is removed by Knowledge of Atman, the state of Moksha is realised then and there, in this very life. It is not to follow after death.

The cause of delusion is the desire in man. The desires generate the thought-waves, and the thought-waves veil the real nature of the Soul which is blissful, immortal, and eternal. When the desires are annihilated, Knowledge of Brahman dawns on the individual.

Knowledge of Brahman is not an action. You cannot reach Brahman even as you cannot reach yourself except by knowing yourself. Knowledge of Brahman is absolute and direct. It is intuitive experience.
