法苑珠林 30.19

30.19

又摩訶衍大寶嚴經云。譬如醫師持藥游行。而自身病不能療治。多聞之人有煩惱病亦復如是。雖有多聞不制煩惱不能自利徒無所用。譬如死人著金瓔珞。多聞破戒被服法衣受他供養亦復如是。

Furthermore, the Mahāyāna Mahāratnakūṭa-sūtra says: 'Just as a physician travels carrying medicines yet cannot cure his own illness, so it is with a person of wide learning who has the disease of defilements: though he has wide learning, he does not restrain his defilements, cannot benefit himself, and it is entirely useless. Just as a dead corpse may be adorned with gold necklaces, so too is one of wide learning who breaks the precepts, wears the Dharma robes, and receives offerings from others.'
