The Taittiriya Upanishad offers a second classification, alongside the three bodies discussed in the previous piece, describing a person as wrapped in five progressively subtler sheaths, or koshas, each one commonly mistaken for the true self before deeper inquiry reveals a subtler layer beneath it. Annamaya kosha, the sheath made of food, is the physical body, sustained by and literally constructed from what is eaten. Pranamaya kosha, the sheath made of vital energy, is the layer of breath and life-force that animates the physical body and departs at death. Manomaya kosha, the sheath made of mind, is the layer of ordinary thought, emotion, and sensory processing. Vijnanamaya kosha, the sheath made of intellect, is the layer of discernment and decisive judgment, closely aligned with buddhi. Anandamaya kosha, the sheath made of bliss, is the subtlest of the five, a layer of deep, contentless well-being most directly accessed in dreamless sleep.
Each sheath is progressively subtler than the last, and the method the Upanishad prescribes is to inquire, at each layer, whether this is the true self, and to notice, each time, that whatever is being examined is still an object of inspection rather than the one inspecting, the same logic as drig drishya viveka applied specifically and systematically to five named layers rather than to experience in general. Even anandamaya kosha, the subtlest and most easily mistaken for ultimate reality given how blissful and expansive it can feel, is ultimately still classified as a sheath, a covering, rather than as the self it covers.
The five-kosha model maps onto the three-body model discussed previously in a fairly direct way: annamaya corresponds to the gross body, pranamaya through vijnanamaya correspond to the subtle body, and anandamaya corresponds to the causal body. The tradition offers both classifications not because they disagree but because each highlights a different aspect of the same layered structure, three bodies emphasising what survives death and what does not, five sheaths emphasising a step-by-step inquiry a practitioner can actually walk through.
With the instrument, the bodies, and the sheaths all mapped, this movement has assembled a complete account of everything the self is not. What remains, once every covering has been examined and set aside, is the subject this series turns to directly next: the specific and startling three-word description Vedanta offers for what is actually left.
