Note 6 — Chapter XVI · ON TO MATHURÂ OR MUTTRA. CONDITION AND CUSTOMS OF CENTRAL INDIA; OF THE MONKS, VIHÂRAS, AND MONASTERIES.
James Legge translation
After Buddha attained to pari-nirvâṇa,6 the kings of the various countries and the heads of the Vaiśyas7 built vihâras for the priests, and endowed them with fields, houses, gardens, and orchards, along with the resident populations and their cattle, the grants being engraved on plates of metal,8 so that afterwards they were handed down from king to king, without any daring to annul them, and they remain even to the present time.
