Through numerous situations and encounters, immigration can be a test of mental fortitude rather than physical ability. In Buddhism, a bodhisattva is considered to be a guide to awakening and to the Pure Lands. "The Buddha declares that we are all bodhisattvas destined to attain full Awakening. It seems that each of us, then, is engaged in 'spiritual immigration'. The Buddha asserts that everyone is a bodhisattva, or a 'spiritual immigrant', who must attain various virtues which ultimately leads to "prajnaparamita", or 'transcendent wisdom'. The existence of Buddhas and Mahasattvas'great beings' who have achieved a high level on the path to awakeninghave created various branches of belief like Mahayana Buddhism, which is a form of 'spiritual immigration'. "Buddhism is a type of immigration from the world of suffering to nirvana...We are all immigrants who, paradoxically, are seeking to and the land in which we already dwell". In terms of 'spiritual immigration', the path of the bodhisattva is a change of mental capacity rather than cosmic location.
