Samādhi in Hinduism is the highest level of meditation, in which the mind becomes still and one-pointed. It is a non-dualistic state of consciousness in which the person meditating, while still physiologically awake, leaves behind the trappings of herself/himself and becomes one with the Self, the ultimate object of meditation (Universe, God, Being, Brahman).
Meditation is Samādhi when it shines with the Object of meditation alone. The thinker and the meditated become one. The separate notions contemplation, contemplated and contemplator vanish... Samādhi or blissful divine experience arises when the ego and the mind are dissolved. It is a state to be attained by one’s own effort. It is limitless, divisionless and infinite. When this experience is realised, the mind, desires, actions and feelings of joy and sorrow vanish into a void.
In Samādhi or Superconsciousness the student gets merged into the Lord. The senses, the mind and the intellect cease functioning. Just as the river joins the ocean, the individual soul mixes with the Supreme Soul. Samādhi bestows Supreme Knowledge, and one is freed from the wheel of births and deaths and gets Kaivalya (Moksha) or liberation.
In samadhi you enter yourself fully conscious, fully alert. And once you are at the centre fully alert, you will never be the same again. Now you will know who you are. Now you will know that your possessions, your actions are just on the periphery; they are just the ripples, not your nature.
Mukti (liberation) is synonymous with the Self.
Honour your Self. Worship your Self. Meditate on your Self. God dwells within you as You.
