佛說目連問戒律中五百輕重事經 1.188

1.188

問：「比丘得向師塚禮不？」答：「得。難曰：『生是我師，已死尚非比丘，唯枯骨而已，何由向禮？』答：『若佛在世應供養恭敬，泥洹後亦是枯骨，何以供養耶？師生以法益人，後亦應恭敬禮拜，有何過也！』」

Question: "May a bhikṣu pay homage facing his teacher's grave or not?"
Answer: "He may. An objection asks: 'In life he was my teacher; once dead, he is not even a bhikṣu, but merely dry bones. On what basis should one face and bow to them?'
Answer: 'If the Buddha was to be venerated and respected when in the world, yet after nirvāṇa there are also dry bones, why venerate them? In life the teacher benefited others with the Dharma; afterwards he should likewise be venerated and bowed to. What fault could there be?'"
