Acharya Prashant addresses a question regarding a quote from Ramana Maharshi about the 'knot of the heart' connecting the sentient and the insentient. He explains that the human being is an impossible confluence of the physical process of the body (the insentient or material) and consciousness (the sentient), which longs for the formless Self it is rooted in. Saints and wise people have always wondered about this connection, speculating that there must be a point where these two meet. They postulated the existence of a 'knot' within, where the material and the immaterial are held together. This knot is the very basis of the human being, who is a mass of suffering and another name for ignorance. Therefore, they said that when this knot is cut asunder, the human being will be liberated. This knot, the speaker clarifies, is the attachment of consciousness to the material. It is where the immaterial gets knotted to the material. However, he emphasizes that this is a model and should not be taken literally. No such material knot exists within the body. If one were to investigate every tissue and cell, one would not find any 'psychic nerves' or a 'Self' within the body, because the immaterial cannot be seen with material eyes. To see the knot, one would have to see both its material and immaterial sides, which is impossible. The quote from Ramana Maharshi, comparing the Self's force to electricity traveling through wires to impart sentience, is a pointer, a model to help understanding. Taking this model literally would mean objectifying the Self, which is not an object or an electrical equipment. The Maharshi's model illustrates that the body is material, yet something beyond the material, like consciousness and understanding, is happening within it. The brain, a material organ, can process information and even attain peace by hearing a Saint's words, which points to a power beyond the material machine itself. The model suggests that the True Self is the source of this 'electricity' (consciousness), which flows through 'psychic wires' (a metaphor) to make the senses sentient. When this connection is disrupted through true knowledge, all that remains is the true, blissful Self, without any attributes. The speaker concludes by advising to grasp the gist of this model without taking it as a literal, material reality, as there is actually no physical knot, no Self within the body, and no psychic wires.
