"For nature is a perpetual circulatory worker, generating fluids out of solids, and solids out of fluids, fixed things out of volatile, & volatile out of fixed, subtle out of gross, & gross out of subtle, Some things to ascend & make the upper terrestrial juices, rivers and the atmosphere; & by consequence others to descend for a requital to the former. And as the earth, so perhaps may the sun imbibe this spirit copiously to conserve his shining, & keep the Planets from receding further from him. And they that will, may also suppose, that this spirit affords or carries with it thither the solary fuel & material principle of light; And that the vast aethereal spaces between us, & the stars are for a sufficient repository for this food of the sun and planets."
