The teachings of the Buddha explicitly encouraged it. Buddhism is the only religion I know of that instructs you to fully abandon it, as once you’ve fully grokked what it has to teach… you won’t need it any more.
IIRC the Buddha said it was like carrying the oar of a boat: once you have used it to get you to your destination (nibbhana), carrying it is needless.
The fish trap exists because of the fish; once you've gotten the fish, you can forget the trap.
The rabbit snare exists because of the rabbit; once you've gotten the rabbit, you can forget the snare.
Words exist because of meaning; once you've gotten the meaning, you can forget the words.
Where can I find a man who has forgotten words so I can have a word with him?
