Patanjali speaks of many different kinds of samadhi, but for practical purposes we may speak of two: savikalpa and nirvikalpa. Arjuna’s vision begins with savikalpa samadhi, in which he sees God in a personal manifestation. Then, as he passes into nirvikalpa samadhi, Arjuna sees all forms disappearing into God, until only a supernatural fire consuming the entire phenomenal world is left.
