Savichara is the state of meditation in which the mind identifies and perceives the object of meditation. The tanmantras, as the five elements are called, are the objects of meditation. As such, the yogi gains an understanding of the elements and nature, as well as time and space.
In the Yoga Sutras, broadly classifies samadhi as samprajnata samadhi (meditation with focus on an object) and asamprajnata samadhi (meditation without an object of focus). Asamprajnata samadhi is the higher state of the two because the consciousness of the yogi merges with the Absolute. Savichara is a type of samprajnata Samadhi.
