Vignanamaya kosa
According to the Kosha system in Yogic philosophy, the nature of being human encompasses physical and psychological aspects that function as one holistic system.
The Kosha system refers to these different aspects as layers of subjective experience. Layers range from the dense physical body to the more subtle levels of emotions, mind and spirit. Psychology refers to the emotional, mental and spiritual aspects of our being.
Together, all aspects make up our subjective experience of being alive
The five sheaths (pancha-kosas) are :
Annamaya kosha – food-apparent-sheath
Pranamaya kosha – air-apparent-sheath
Manomaya kosha – mind-stuff-apparent-sheath
Vignanamaya kosha – wisdom-apparent-sheath (Vignana)
Anandamaya kosha – bliss-apparent-sheath (Ananda)
