大方便佛報恩經 6.113

6.113

答曰：「凡是本生因緣，不可依也。此中說者，非是修多羅，非是毘尼，不可以定實義也。又云：『此或是迦旃延以度億耳故，作此變化感悟其心，非是實事。』若受齋已，欲捨齋者，不必要從五眾而捨。若欲食時，趣語一人，齋即捨也。

[The Buddha] replied: "Any past life conditions cannot be relied upon [as standard]. What is spoken therein is neither sūtra nor vinaya, and cannot determine the true principle. It is also said: 'This was perhaps Kātyāyana, who in order to deliver Koṭīkarṇa manifested these transformations to awaken his mind; it was not an actual fact.' If having received the observance one wishes to renounce it, it is not necessary to renounce it before [a member of] the five assemblies. When one wishes to eat, merely speaking to a single person, the observance is immediately renounced."
