Heaven is eternal and Earth everlasting. They can be eternal and everlasting because they do not exist for themselves, And for this reason can exist forever.
We are never without a pilot. When we know not how to steer, and dare not hoist a sail, we can drift. The current knows the way, though we do not. The ship of heaven guides itself, and will not accept a wooden rudder.
Everything that has name and form must begin in time, exist in time, and end in time. These are settled doctrines of the Vedanta, and as such the heavens are given up.
We thought of life by analogy with a journey, a pilgrimage, which had a serious purpose at the end, and the thing was to get to that end, success or whatever it is, maybe heaven after you’re dead. But we missed the point the whole way along. It was a musical thing and you were supposed to sing or to dance while the music was being played.
The holy heaven yearns to wound the earth, and yearning layeth hold on the earth to join in wedlock; the rain, fallen from the amorous heaven, impregnates the earth, and it bringeth forth for mankind the food of flocks and herds and Demeter's gifts; and from that moist marriage-rite the woods put on their bloom.
