Ascetics of Hinayana Buddhism (the Lesser Vehicle) aim to escape from our world of sorrows, stand aloof from its problems, and attain a pure state of consciousness. This can make them indifferent to the world. They easily forget to fulfill the most important task in religion, namely, to save ordinary people.

On the other hand, Mahayana Buddhism (the Great Vehicle), beginning from the point of view of ordinary people, asserts that the state of enlightenment can be realized only in the midst of this world, because Bodhisattvas cannot save people without living and working here where evil and misery exist. Bodhisattvas, of course, are themselves pure, and they are never contaminated by the vice and evil of their environments. They are like lovely lotus flowers, which rise from out of the mud at the bottom of the water.
