Mv 3.1
Translated from the Pâli by T. W. Rhys Davids and Hermann Oldenberg
1. At that time the Blessed One dwelt at Râgagaha, in the Veluvana, in the Kalandakanivâpa. At that time the retreat during the rainy season had not yet been instituted by the Blessed One for the Bhikkhus. Thus the Bhikkhus went on their travels alike during winter, summer, and the rainy season.
2. People were annoyed, murmured, and became angry, saying, 'How can the Sakyaputtiya Samanas go on their travels alike during winter, summer, and the rainy season? They crush the green herbs, they hurt vegetable life, they destroy the life of many small living things. Shall the ascetics who belong to Titthiya schools, whose doctrine is ill preached, retire during the rainy season and arrange places for themselves to live in? shall the birds make their nests on the summits of the trees, and retire during the rainy season, and arrange themselves places to live in; and yet the Sakyaputtiya Samanas go on their travels alike during winter, summer, and the rainy season, crushing the green herbs, hurting vegetable life, and destroying the life of many small things?'
3. Now some Bhikkhus heard those people that were annoyed, murmured, and had become angry. These Bhikkhus told this thing to the Blessed One. In consequence of that and on this occasion the Blessed One, after having delivered a religious discourse, thus addressed the Bhikkhus: 'I prescribe, O Bhikkhus, that you enter upon Vassa.'
