Note 5 — LECTURE I. Introductory. Buddhism in relation to Brāhmanism.
Reading edition
The Sāṅkhya system, as I have shown, was closely connected with the Vedānta, though it recognized the separate existence of countless individual Purushas or spirits instead of the one (called Ātman). Both had much in common with Buddhism, though the latter substituted Ṡūnya ‘a void’ for Purusha and Ātman.
