It's always necessary to know when a stage of one's life has ended. If you stubbornly cling to it after the need has passed, you lose the joy and meaning of the rest. And you risk being shaken to your senses by God.
If you practice in accord with your individual capacity, little by little you will find more pleasure and joy in it. As you gain inner strength, your positive actions will gain in profundity and scope.
Things in which we do not take joy are either a burden upon our minds to be got rid of at any cost; or they are useful, and therefore in temporary and partial relation to us, becoming burdensome when their utility is lost; or they are like wandering vagabonds, loitering for a moment on the outskirts of our recognition, and then passing on. A thing is only completely our own when it is a thing of joy to us.
There is, of course, no joy so great as the cessation of pain; in fact all joy, active or passive, is the cessation of some pain, since it must be the satisfaction of a longing, even perhaps an unconscious longing.
But that had been grief--this was joy. Yet that grief and this joy were alike outside all the ordinary conditions of life; they were loopholes, as it were, in that ordinary life through which there came glimpses of something sublime. And in the contemplation of this sublime something the soul was exalted to inconceivable heights of which it had before had no conception, while reason lagged behind, unable to keep up with it.
