Michael Washburn states that the "Yogasutras" text identifies stepwise stages for meditative practice progress, and that "Patanjali distinguishes between Dharana which is effortful focusing of attention, Dhyana which is easy continuous one-pointedness, and Samadhi which is absorption, ecstasy, contemplation". A person who begins meditation practice, usually practices "Dharana". With practice he is able to gain ease in which he learns how to contemplate in a sharply focussed fashion, and then "he is able more and more easily to give uninterrupted attention to the meditation object; that is to say, he attains Dhyana". With further practice, the yogi "ceases being detachedly vigilant" and enters "a state of fusion with the meditation object" which is Samadhi.
