As man came to this globe from another planet, though of course then a being of very great power before being completely enmeshed in matter, so the lower kingdoms came likewise in germ and type from other planets, and carry on their evolution step by step upward by the aid of man, who is, in all periods of manifestation, at the front of the wave of life. The Egos in these lower kingdoms could not finish their evolution in the preceding globe-chain before its dissolution, and coming to this they go forward age after age, gradually approaching nearer the man stage. One day they too will become men and act as the advance guard and guide for other lower kingdoms of this or other globes. And in the coming from the former planet there are always brought with the first and highest class of beings some forms of animal life, some fruits and other products, as models or types for use here. It will not be profitable to go into this here with particularity, for being too far ahead of the time it would evoke only ridicule from some and stupidity from others. But the general forms of the various kingdoms being so brought over, we have next to consider how the differentiation of animal and other lower species began and was carried on. This is the point where intelligent aid and interference from a mind or mass of minds is absolutely necessary. Such aid and interference was and is the fact, for Nature unaided cannot do the work right. But I do not mean that God or angel interferes and aids. It is Man who does this. Not the man of the day, weak and ignorant as he is, but great souls, high and holy men of immense power, knowledge, and wisdom. Just such as every man would now know he could become, if it were not that religion on one hand and science on the other have painted such a picture of our weakness, inherent evil and purely material origin that nearly all men think they are puppets of God or cruel fate without hope, or remain with a degrading and selfish aim in view both here and after. Various names have been given to these beings now removed from our plane. They are the _Dhyanis_, the Creators, the Guides, the Great Spirits, and so on by many titles. In theosophical literature they are called the _Dhyanis_.
