In the course of conversation with a learned man who asked about Purusha and Prakriti, Sri Bhagavan said:
Purusha and Prakriti are only the bifurcation of the one Supreme. They are surmised because the student has the sense of duality deep rooted. The same “Gita” also says that Purushottama lies beyond Purusha and Prakriti.
D.: What are parā-nādi, sushumna nādi and the Heart?
M.: “But resolves into the parā”. (“Sushumnātu pareleena”). Heart is usually undertsood to be the muscular organ lying on the left of the chest. The Modern Psychological Review speaks of the physical organ on the left and the Heart centre on the right. The Bible says that a fool’s heart is on the left and a wise man’s on the right. “Yoga Vasishta” says that there are two hearts; the one is Samvit; and the other the blood-vessel.
D.: What is anāhata?
M.: Anāhata is the chakra lying behind the heart. It is not Samvit. “Lalita Sahasranama” has it, anāhata chakrasthāyai namo namah (Salutations to the core situated in Anāhata) and the next mantra (in the Heart). Thus it is clear that anāhata is not the same at Hrit.
