The inhabitants of the C part of the seventh world are extremely intelligent — far more intelligent than the human beings of our earth; so much so that they are capable of expressing their thoughts without gross means. The inhabitants of the B part are also more intelligent than the people of our world, but not so intelligent as those of C. But though A — our earth — is inferior from the standpoint of intellect to both B and C, it is certainly superior to them from the standpoint of love and high emotions. Whereas the inhabitants of C have one hundred per cent intellect and zero per cent love, and those of B have seventy-five per cent intelligence and twenty-five per cent love, the people of our earth have, on an average, intelligence and love in equal proportions. When one, subduing intellect, gets one hundred per cent love, one realizes God.

When the Atman leaves its highest form in C, it takes the highest form in B; and after giving it up in B, it incarnates in the highest form on our earth. Therefore, evolution, strictly speaking, ends on our earth, but the Atman has to go on reincarnating in the human form till it knows itself; i.e., till God is realized.

Now, just as there is evolution of drop-bubbles, so also there is evolution and reaction of wave-bubbles. The moon, which gives us light at night, was once an earth, just like our earth; and there are a number of such cooled-down earths. Millions of years ago the condition of our earth was quite different from its present condition, and millions of years hence, it will be just like the moon. About the time our earth turns into a moon, it will slip aside from its present position, just as the preceding one did; and its place will be filled by the B part of the seventh world. C will take the place of B and the world number 6 will take the place of C, and so on. Needless to say that with the evolution of wave-bubbles (worlds) the evolution of drop-bubbles goes on simultaneously. In the world number 6 at present there are no human beings, but when it will take the place of C, souls, after giving up the highest animal form, will incarnate in the human form with extraordinary intellect. Similarly when B will take the place of our earth, its inhabitants will be filled with more love and imbued with higher emotions than they have at present.
