Five layers, from body to inner experience
In Vedantic teaching, a kosha is a “sheath” or covering used to describe how the self seems entangled with different layers of human experience. The familiar five-layer model moves inward: the physical body, sustained by food; the vital functions associated with breath and energy; the mind, with its feelings and everyday thoughts; the intellect, which judges and makes sense of experience; and the layer of bliss, associated with deep rest and inner ease.
These are not usually presented as five literal objects wrapped around a soul. They are a teaching map: each layer is something a person can notice, while Vedanta asks what, if anything, is aware of them all.
Why the “bliss” layer is still a sheath
The innermost layer can sound like the final, perfect self, but in this model even bliss is temporary and conditioned. A person may feel ease in deep sleep or meditation, for example, but that state comes and goes. The underlying self—often called Atman—is not meant to be another passing mood or sensation.
The point of working through the koshas is therefore not to reject the body or ordinary life. It is to loosen the habit of saying “I am only this body,” “I am my thoughts,” or “I am my judgments.” The practical implication is a shift in attention: instead of treating every changing experience as the whole self, the practitioner learns to observe it as one layer of experience.
