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.'

Brahmacariya sutta - The Spiritual Life

"Bhikkhus, this 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.' Rather, bhikkhus, this spiritual life is led for the purpose of restraint, for the purpose of letting go, for the purpose of dispassion, and for the purpose of cessation.

For the purpose of restraint, for the purpose of letting go, the spiritual life is not based on tradition; The Blessed One taught the spiritual life, leading to and grounded upon Nibbāna; This is the path followed by the illustrious ones, traveled by the great sages.
Whoever practices it, as taught by the Buddha; will make an end to suffering, fulfilling the teacher's instruction."
