Vayu Granthi refers to a knot or energetic blockage associated with the air element (Vayu) in the subtle body. It signifies an obstruction that affects the flow of prana (life force energy) and breath within the energetic system. This term underscores how such blockages can impact respiratory functions, mental clarity, and the overall flow of vital energy throughout the body. Addressing Vayu Granthi through practices like pranayama and meditation aims to restore balance and promote harmony in the subtle energy channels related to air element energies.
