Visuddhi Chakra is violet in color, round, and has 16 petals. Vishudhi is the purification center and is known as the fountain of youth. Nectar of life falls from Bindu into this chakra, generating health, vitality, and longevity.
Vishuddhi is associated with vijnanamaya kosha, when vishuddhi is purified, the sense of hearing becomes very sharp not only through the ears but through the mind too. Vishuddhi is located behind the throat pit in the spine and is associated with the thyroid gland.
By meditating on vishudhhi, the mind becomes free of thought, pure and empty like space. Asanas that press the muscles in the neck and throat help in balancing the energy of the throat chakra.
