Parā Vidyā (Sanskrit: परा विद्या) is a combination of two words – parā, in Hindu philosophy, means - existence, paramount object, the highest point or degree, final beatitude; and vidyā means - knowledge, philosophy, science, learning, scholarship.Para Vidya means – higher learning or learning related to the Self or the Ultimate Truth i.e. transcendental knowledge.Vedanta affirms that those who gain the knowledge of the Self attain kaivalya, they become liberated, they become Brahman.
Saunaka, having asked – कस्मिन्नु भगवो विज्ञाते सर्वमिदं विज्ञातं भवतीति (" Revered Sir, what is that by the knowing of which all this becomes known? "), - was told by Angiras that –
there were two different kinds of knowledge to be acquired – 'the higher knowledge' or Para Vidya (Sanskrit: परा विद्या )and 'the lower knowledge' or Apara Vidya. The lower knowledge consists of all textual knowledge - the four Vedas, the science of pronunciation etc., the code of rituals, grammar, etymology, metre and astrology. The higher knowledge is by which the immutable and the imperishable Atman is realized, which knowledge brings about the direct realization of the Supreme Reality, the source of All. The knowledge of the Atman is very subtle; it cannot be obtained out of one’s own effort; the Atman cannot be intuitively apprehended by mere intellectual equipments. Thus, Angiras draws the distinction between the way of knowledge and the way of realization, as between opinion and truth. For understanding this for realizing the Reality the aspirant must seek a teacher. The teacher who has already realized his identity with the Atman alone can impart this much sought-after wisdom on the strength of his own experiences.
A human being is blessed with the faculty of self-knowledge which is Apara Vidya or logical reasoning and also with the faculty of understanding and self-awareness which is Para Vidya or quantum logic. Para Vidya is defined as the intuitive vision of non-duality; it is the transcendental knowledge which is beyond all limits of knowledge, experience and reason, which is, beyond intellect, mind and sense. The Absolute, which is Truth, which is Reality, is neither an expression nor a reflection of itself; it is non-dual being devoid of otherness, and it cannot be an object of knowledge in the ordinary sense as it surpasses the intellect in subtleness. Knowledge is truth and truth is correspondence of an apprehension with its object. It is the intellect which moves within the sphere of duality resulting in delusion, wrong identification etc. Para Vidya is the intuitive level of vidya that stems from a unity, and manifests as a vision, manifests as an experience.
