The last of the five koshas is anandamaya kosha—the bliss sheath. Anandamaya encompasses not the feeling of bliss, but rather, the experience of bliss. In contrast to vijnanamaya kosha, you do not witness the bliss sheath, you are the bliss. Bliss can be thought of not as an ecstatic happiness or even joy, but a steady state of being, no matter what circumstance arises.
The state of wholeness, of integration with the moment and with yourself, encompasses the inner sheath of anandamaya. This bliss state is usually experienced in fleeting moments, but can remain for longer periods. Importantly, anandamaya is still a sheath, a layer that can be peeled back. When anandamaya is peeled away, we reach atman—our very center. Atman is our direct connection with the divine, with the essence of all that is. It is our pure consciousness.
Anandamaya pervades each of the previous outer sheaths, but is only experienced once we are able to peel the illusions of each sheath away to reveal our true nature. Anandamaya can be experienced in those moments when you are wholly immersed in that which you are doing—when you no longer separate yourself from your experience.
Striving to reach anandamaya kosha is a futile attempt, for it is only revealed when we release any form of mind control over it. Anandamaya is not of the mind. It is a deeper experience than that which can be contemplated. Even describing it in words is not completely accurate. The bliss of a child fully immersed in the moment—that is anandamaya.
