中天竺舍衛國祇洹寺圖經 2.10

2.10

On the three sides—east, west, and north—of the Buddha Courtyard, long alleys run in a continuous line, without side doors. To the south, following the great wall, doors open in corresponding directions, leading to the main alley. On three sides of the long alleys, eight rows of trees interlace above, their branches and leaves casting shade, concealing the sangha from view. Circling to the left in front of the Buddha is the usual rule; turning east and wheeling north is the heavenly constant, and ascends and turns above the ground, as may be deduced by analogy.
