And of this glory, we in our physical brain-workings get but a faint reflection, somewhat as the moon gets a faint reflection of the glory of the sun and transmits it as moonlight to our earth. Huxley, then, sets forth with graphic truth the biologic karma merely of the body, as transmitted as effect from parent to offspring, through the working of the aggregate of the lower life-atoms, in their preparing of vehicles for incoming souls of similar tendencies, of similar character. It is an old, old conception. Taking this factor into account, we have as it were a thumbnail sketch of the whole doctrine of the process of reincarnation. It is unquestionable that children take after parental and ancestral types.
Nobody denies the fact.
What we call heredity is simply the carrying on from generation to generation of certain traits or biases or peculiarities or deformities or symmetries from father to son to son to son. Admitting then that the studies of heredity have shown the coming together of similar types in a family milieu, the theosophist points out that such assemblings of similar individuals is brought about by psychomagnetic attraction. It is attraction which brings people together. When the entity is ready to reincarnate, it is drawn psychomagnetically, instinctually if you like, to the family, to the womb, most sympathetic to its vibrational rate. Thought and reflection, study and examination, will show you that the immense likelihood is that you will be attracted to the family milieu, to the family environment, which offers you the closest vibrational rate to your own.
