The first one is the separation from worldly impressions, thanks to perfect knowledge. The second one is due to destruction of passion (passionate attachment) whereby the liberated soul attains Kaivalya, because even the Lihga Sarlra (the subtle inner body) is absent. Through Kaivalya he becomes Niranjana (unsullied). By not being sullied, he becomes Suddha (pure). In this state of liberation there is no guide or leader. The third type of cause of liberation is by the destruction of Tffnd (thirst) (for enjoyment) .
