Patanjali further divides samadhi into two categories: samprajnata samadhi and asamprajnata samadhi. Samprajnata samadhi is meditation in which an object is the focus. Meditation without an object to focus upon is asamprajnata samadhi, which is the higher form of samadhi. Savitarka is a type of samprajnata samadhi.
In the initial stages of savitarka, the mind focuses on an object. At this level, the mind contemplates the appearance of the object, its name, its sound and other information about it. Although the mind is still active in savitkara, the association with the object deepens and goes beyond its normal state, while the mind stays focused and does not wander to another object.
