The words in italics being equivalents in the Sanscrit language adopted by him for the English terms. This classification stands to this day for all practical purposes, but it is capable of modification and extension. For instance, a later arrangement which places Astral body second instead of third in the category does not substantially alter it. It at once gives an idea of what man is, very different from the vague description by the words “body and soul,” and also boldly challenges the materialistic conception that mind is the product of brain, a portion of the body. No claim is made that these principles were hitherto unknown, for they were all understood in various ways not only by the Hindus but by many Europeans. Yet the compact presentation of the sevenfold constitution of man in intimate connection with the septenary constitution of a chain of globes through which the being evolves, had not been given out. The French Abbé, Eliphas Levi, wrote about the astral realm and the astral body, but evidently had no knowledge of the remainder of the doctrine, and while the Hindus possessed the other terms in their language and philosophy, they did not use a septenary classification, but depended chiefly on a fourfold one and certainly concealed (if they knew of it) the doctrine of a chain of seven globes including our earth. Indeed, a learned Hindu, Subba Row, now deceased, asserted that they knew of a sevenfold classification, but that it had not been and would not be given out. Considering these constituents in another manner, we would say that the lower man is a composite being, but in his real nature is a unity, or immortal being, comprising a trinity of Spirit, Discernment, and Mind which requires four lower mortal instruments or vehicles through which to work in matter and obtain experience from Nature. This trinity is that called _Atma-Buddhi-Manas_ in Sanscrit, difficult terms to render in English. _Atma_ is Spirit, _Buddhi_ is the highest power of intellection, that which discerns and judges, and _Manas_ is Mind. This threefold collection is the real man; and beyond doubt the doctrine is the origin of the theological one of the trinity of Father, Son, and Holy Ghost. The four lower instruments or vehicles are shown in this table: _Atma_, {The Passions and Desires, _Buddhi_, {Life Principle, _Manas_, {Astral Body, {Physical Body.
