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.

Atha kho so puriso taṃ kulhiraṃ āropetvā pāre gaccheyya. Tam-enaṃ loko ‘kiṃsu, bho, karissati kulhirena pāraṃ gato’ti? Evaṃ, bhikkhave, dhammaṃ desitaṃ ājānāsi: ‘pāraṅgamanaṃ dhammaṃ, anupagamma dhamma’ti.
