Note 3 — Chapter XXX · THE ŚRATAPARṆA CAVE, OR CAVE OF THE FIRST COUNCIL. LEGENDS. SUICIDE OF A BHIKSHU.
James Legge translation
The Chinese characters used for the name of this cavern serve also to name the pippala (peepul) tree, the ficus religiosa. They make us think that there was such a tree overshadowing the cave; but Fâ-hien would hardly have neglected to mention such a circumstance.
