"4. Up till now the inner man has identified himself with his forms and with their active modifications. These forms are the modifications mentioned in the various translations, conveying the subtle [12] truth concerning the infinite divisibility of the atom; these are the veiling sheaths and rapidly changing transformations which prevent the true nature of the soul becoming manifest. These are the externalities which hinder the light of the inner God from shining forth, and which are occultly spoken of as "casting a shadow before the face of the sun." The inherent nature of the lives which constitute these active versatile forms has hitherto proved too strong for the soul (the Christ within, as the Christian puts it) and the soul-powers have been prevented full expression. The instinctual powers of the "animal soul," or the capacities of the aggregate of lives which form the sheaths or bodies, imprison the real man and limit his powers... He becomes "enmeshed in their activities" and must free himself before he comes into his heritage of power and peace and bliss."
