Full context:   According to Makransky the Mahayana Bodhisattva ideal created tensions in the explanation of the four truths. In the Mahayana view, a fully enlightened Buddha does not leave samsara, but remains in the world out of compassion for all sentient beings. The four truths, which aim at ending samsara, do not provide a doctrinal basis for this view, and had to be reinterpreted. In the old view, klesas and karma are the cause of prolonged existence. According to Makransky, "[t]o remove those causes was, at physical death, to extinguish one's conditioned existence, hence to end forever one's participation in the world (Third Truth)." According to Makransky, the question of how a liberated being can still be "pervasively operative in this world" has been "a seminal source of ongoing doctrinal tension over Buddhahood throughout the history of the Mahayana in India and Tibet."
