Granthis are energetic knots or blockages in the subtle body that obstruct the flow of prana (life force energy) through the nadis (energy channels) and chakras. In yogic and tantric traditions, there are three main granthis: Brahma Granthi (root and sacral chakras), associated with physical attachments; Vishnu Granthi (solar plexus and heart chakras), linked to emotional attachments; and Rudra Granthi (throat and third eye chakras), connected to attachments to psychic powers and spiritual experiences. Yoga, pranayama, and meditation practices aim to release these knots, facilitating the free flow of energy and leading to spiritual awakening.
