Note 56 — LECTURE VI. The Morality of Buddhism and its chief aim—Arhatship or Nirvāṇa.
Reading edition
It must not be inferred that the episode of the Bhagavad-gītā is of great antiquity. This point I have made clear in ‘Brāhmanism and Hindūism’ (p. 63) as well as in ‘Indian Wisdom.’ My object at p. 138 is simply to show that Nirvāṇa is an expression common to Buddhism, Brāhmanism, and Hindūism.—Corr.
