Ancient sages have explored the depths of our being, and given us the knowledge of the Pancha Kosha (five sheaths), that addresses every level of a human being.
Pancha Kosha comprises:
Food sheath (Annamaya Kosha)
Breath sheath (Pranamaya Kosha)
Mind Sheath (Manomaya Kosha)
Intellect sheath (Vijnyanamaya Kosha)
Bliss Sheath (Anandamaya Kosha)
