Samadhi is the state of consciousness that is reached when during the meditation the person feels that he is merging with the universe, with all the existences. In various East Asian religious and mystical traditions - such as Hinduism, Buddhism, Jainism, Sikhism and yoga groups - samādhi is considered a state of consciousness of meditation, contemplation or recollection in which it is felt to achieve unity with the divine.
