‘Apanbodh’ is self-perception — sort of innate understanding. Only when one dwells in pure I-ness does the feeling of this perception occurs. Self perception is esse of the pure I-ness, and the perception of Swabhava (nature) is in my-ness. In this treatise, existence of both of these has been elaborated by through the innate perception. Spontaneous self perception is self-realizable by the innate perception only. Sri Sri Babathakur has unfolded the Science of Self-realization in this treatise, spread over two chapters, in His own inimitable style.
