VIII. Man's First Ancestors

With the increasing solidification of physical matter, the soul-nature gradually lost control over its formation. The bodies already formed could only reproduce bodies after their own image. A change now occurs in the manner of generation, that is to say, the offspring of the mother-being appears considerably smaller, only growing gradually to the size of the parent. Organs of generation now begin to appear, whereas hitherto they had not existed. Henceforward it is no mere physico-chemical process which takes place within the form. Such a process is now no longer sufficient for the purpose of generation: for the outer matter, growing denser and denser, is no longer capable of being directly influenced by the soul. A special portion within the form is therefore set apart for this function, being withdrawn from the immediate influence of the outside material world. Only the body, exclusive of the specialised part, is still exposed to these influences; and it remains in the condition which was formerly that of the whole body. In the specialised part the psychic nature continues to work, and the soul becomes at this point the vehicle of the life-principle (called in Theosophical literature “Prâna”).
