Answer: And we do not look back. We want to return to the point of unity in our new egoistic state. This is no longer the return to the past. We do not want to be in the past!
Today we wish to return to that state, which we left, in our grown egoism. And when we return to it with our real egoism, it is a new, stronger, clearer state.
Otherwise, there is nothing. The whole difference between spiritual steps is only in the added egoism.
