After Prince Jayasena expresses disbelief about the possibility of attaining unification of mind, the Buddha explains why a life of sensual pleasure blinds one to spiritual truths using two vivid similes.

Using the simile of an elephant’s footprint, the Buddha illustrates how confidence in him develops gradually through practice.

The spiritual life is not lived for the purpose of deceiving people, nor for the purpose of winning favor with people, nor for the sake of acquisitions, respect, and popularity, nor for the thought ‘Let people know me.’ But rather, this spiritual life is lived for the purpose of restraint and for the purpose of letting go.
