I reached in experience the nirvana which is unborn, unrivalled, secure from attachment, undecaying and unstained. This condition is indeed reached by me which is deep, difficult to see, difficult to understand, tranquil, excellent, beyond the reach of mere logic, subtle, and to be realized only by the wise.
Gautama BuddhaA virtuous man or woman who is determined to develop the Supreme Enlightened Mind, should thus develop it: I have to lead all living beings to put a stop to (reincarnation) and escape (suffering), and when they have been so led, not one of them in fact stops (reincarnating) or escapes suffering. Why? Because, if a Bodhisattva believes in the notion of an ego, a personality, or a living being, he is not a true Bodhisattva.
