A golden chain is as much a chain as an iron one. There is a thorn in my finger, and I use another to take the first one out; and when I have taken it out, I throw both of them aside; I have no necessity for keeping the second thorn, because both are thorns after all. So the bad tendencies are to be counteracted by the good ones, and the bad impressions on the mind should be removed by the fresh waves of good ones, until all that is evil almost disappears, or is subdued and held in control in a corner of the mind; but after that, the good tendencies have also to be conquered. Thus the "attached" becomes the "unattached". Work, but let not the action or the thought produce a deep impression on the mind. Let the ripples come and go, let huge actions proceed from the muscles and the brain, but let them not make any deep impression on the soul.
