Where the distant edge of the anandamaya kosha (the subtlest aspect of human creation) blends with the final two layers of existence (sat and chit), these three layers make up the threefold reality of Purusha itself. Sat-chit-ananda is literally absolute existence-pure consciousness-perfect bliss (on lower levels, in the subtle body, this corresponds to präna-tejas-ojas, and in the physical body, to väta-pitta-kapha).
