[103] Now at that time the group-of-six bhikkhus (chabbaggiyā bhikkhū) stayed apart from their sitting cloths (nisīdana) for four months. They reported this matter to the Blessed One. "Bhikkhus, one should not stay apart from a sitting cloth for four months. Whoever should stay apart from it commits an offense of wrong-doing (dukkaṭa)."
