No one can remain even for a moment without activity, but usually actions that lead to complications and misery. Swami Paramananda explains what right action is and how it can solve our problems.
There is only one sin -- and that sin is weakness. When I was a boy, I read Milton's Paradise Lost. The only good man I had any respect for was Satan. The only saint is the soul who never weakens, faces everything, and determines to die game.
-Swami Vivekananda
