Knots : Granthis
The ancient Vedic and Upanisadic thinkers have mentioned about the knots or granthis. The most prominent of these is said to be the hrdaya granthi or the heart-knot. This has to be broken or cut, and then alone one is said to be free. The usual meaning for this is that our attachments produce knots of affection, and these prevent our getting dispassionateness. Renunciation, Vairagya, is thus said to help in the cutting of this knot. In fact if one pierces the hydra granthi one's doubt are said to get dissolved. This is the role of knowledge, in addition to the former role of affection. Hrdaya granthi therefore is a very important obstacle and has to be cut.
There are tow others who consider that there are three knots, the knot of Brahma or creative faculty, of progeny, the knot of Visnu, the attachment to live on for ever or preserve oneself; and the knot of Rudra-the fear of death which produces its own kind of attachment. These three knots are usually placed at the navel plexus, the Cardiac plexus, and the Ajna centre, the plexus at the middle of the eyebrows. When the susumna Kundalini pierces through these three knots and rises to the highest place at the crown of the head, one begins to be free from attachment to the three worlds, the bhuh, bhuvah and svar, the terrestrial, the middle and the celestial worlds.
The origination of the knots is nowhere given. They may be considered to be the points of intersection of the three levels of being, and they produce divisions and distinctions between the levels of experience. One has to pass from one to the other if those experiences are to take place. Sri Ram Chandra, in his book "Anant ki Or" has revealed how these knots form the original thought-force or energy as it moves out centripetally in the form of vibrations and waves.* As vibrations they have the sound, and as waves they have light. These two properties are there, becoming grosser and grosser, and becoming many rayed as they move out from the Centre, and thought-energy itself becomes more and more energetic as it moves out from the centre. So much so, we are aware of energy or force more than thought in grossest manifestation of matter as particles.
