It is in the union of the Ascending and the Descending currents that harmony is found, and not in any war between the two. It seems that only when the Ascending and the Descending are united can both be saved. And if we - if you and I - do not contribute to this union, then it is very possible that not only will we destroy the only Earth we have, we will forfeit the only heaven we might otherwise embrace.
