To condense, he now proceeds to build up for himself a new body for his coming life on the lower mental level. "This again exactly represents his desire nature, faithfully reproducing the qualities he evolved in the past; ... thus the man stands fully equipped for his next incarnation.... Meanwhile action external to himself is being taken to provide him with a physical body suitable for the expression of his qualities.... All this is done by certain mighty spiritual Intelligences often spoken of as the lords of Karma because it is their function to superintend the working out of causes continually set going by thoughts, desires and actions. They hold the threads of destiny which each man has woven, and guide the reincarnating man to the environment determined by his past. The race, the nation, the family thus determined, what may be called the mould of the physical body ... is built within the mother's womb by the agency of an elemental, the thought of the Karmic lords being its motive power." The difficulties which this statement evades are enormous, its conjectures are even more enormous. This is the subversion of all the facts of biology and heredity to a capricious scheme, built up just to answer a few practical questions--Why do we differ? Why do we suffer? Why are we happy? Surely there are far more simple and reasonable answers to these questions than the answer of Theosophy, and the willingness of so many people to rest in such an answer as this can prove only one of two things--the capacity of the mind for credulity or the arresting failure of those whose business it is to interpret life to the perplexed, to have even begun their task. _Immortality a Nobler, Juster and Simpler Balancing of Life's Account-Book_ If there be a want of opportunity in our present existence for a true balancing of the scales of justice, and if some future existence be needed to make things right, then the Christian doctrine of immortality has an immense advantage over the reincarnations of Theosophy. We have no right to underestimate the difficulties of a reasonable faith in immortality, but they are simplicity itself as compared with the difficulties of reincarnation, for reincarnation must answer every question which the possibility of immortality raises and answer even more difficult questions of its own. It is far simpler to believe that having survived the shock of death we go on with the same essential individuality we had before death, than to believe that having survived we are sent back again through the gates of birth and are really reincarnated in another individuality. More than that, the Christian belief in immortality is more ethical. The action and reaction of life have real meaning for me only as I know and remember. No theosophic evasion can take the force out of this.
