When man begins his long pilgrimage, a form is ready for his ensouling, prepared to receive and to respond to the impulses which come to it from the physical, astral and--to a small extent--from the mental planes. His physical atoms are considerably evolved, the sensory sheath is working actively, and there is a very imperfect lower mental sheath; these have been built up through the evolution of the animal realm. Do not fall into the mistake of the western way of thinking, and say that man descends from the animal; that is not true. It is only a fragment of truth half seen and thereby distorted. What is true is this: that the matter of his lower vehicles has been prepared by evolving through the stages of the elemental, mineral, vegetable and animal kingdoms, in order that it may be builded into the form of man; that _in previous kalpas_ forms had been evolved that might fairly be described as half-ape, half-human, that were never occupied by the triple Self, and that therefore belonged to the animal, not to the human kingdom; that in the present cycle the human form evolved, as a fœtus evolves, passing rapidly through the lower stages on the way to the human, as in pre-natal life, and it therefore has stamped upon it the stages through which it has passed. I have been going over, roughly and swiftly, those stages through which the matter of which the body is composed has gone in the past, and you will see that the true theory of evolution is different from the somewhat crude view that there is a regular succession of births from the animal into the man. The matter has been made plastic in the animal, but man in his form is the result of a higher working; the germ of his life can never develop into the animal, but only into the human, because more has been infolded into it, and that germ must unfold along a line which is that of direct human growth. Remembering that, to prevent a possible misconception, we turn to the human centre that is now definitely formed. We speak of its encircling form as the causal body, or Karana Sharîra, the form by which the Self is limited; the Karana Sharîra is not the Self, remember, but is the containing vehicle of the triple Self, and the organ of one aspect of that Self, the aspect of knowledge, shown forth as intelligence. This sheath is important, being relatively of a permanent nature, and it goes on from birth to birth; death cannot touch it, birth cannot modify it; it is the treasure-house or receptacle of all the qualities acquired by experience through human evolution, and passes through the whole cycle of re-incarnations; it is the special _human_ characteristic. The form begins to adapt itself more and more to the life, and here comes in a growing difficulty. The characteristic of the life of man is the life of the intellect; this the specifically human part of evolution; but the life of sensation is far more vivid and tumultuous in the beginning, and
