Vinayapiṭaka · Cūḷavagga (1) · Vol. 6 · Section 529

[529] Bhikkhus, here again, a bhikkhu, while undergoing probation (parivāsa), commits several saṅghādisesa offenses in the interim and, not having concealed them, disrobes. Being ordained again, he does not conceal those offenses. That bhikkhu should be sent back to the beginning (mūlāya paṭikassitabbo).
