Quotes:Pancha Kosha
H. P. Blavatsky
Pancha Kosha. The five “sheaths”. According to Vedantin philosophy, Vijnânamaya Kosha, the fourth sheath, is composed of Buddhi, or is Buddhi. The five sheaths are said to belong to the two higher principles — Jivâtma and Sâkshi, which represent the Upathita and An‐ upahita, divine spirit respectively. The division in the esoteric teaching differs from this, as it divides man’s physical‐metaphysical aspect into seven principles.
