Asana keeps this kosha healthy and can be used to treat problems that arise in the body. Pranamaya Kosha: The next sheath is the life force/energy sheath. It is concerned with the breath and the flow of energy through the body. Pranayama practice is prescribed to address this layer. Manomaya Kosha: The next sheath is the mind or mental sheath. It has to do with thoughts and emotions. It is maintained through meditation. Vijnanamaya Kosha: is the knowledge sheath. This kosha is comprised of your wisdom, intuition, and perception. Meditation is also the key to this layer. Anadamaya Kosha: The innermost sheath is the bliss sheath. It represents unending joy, love, peace, and complete happiness.
