[357] Bhikkhus, "I am" — this is a proliferation (papañcita); "I am this" — this is a proliferation; "I shall be" … "I shall not be"; "I shall be possessed of form"; "I shall be formless"; "I shall be percipient"; "I shall be non-percipient"; "I shall be neither percipient nor non-percipient" — this is a proliferation. Proliferation, bhikkhus, is a disease; proliferation is a tumour; proliferation is a dart. Therefore, bhikkhus, [you should train thus:] "We shall dwell with a mind (citta) free from proliferation." For thus, bhikkhus, should you train.
