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.
Be strong! ... You talk of ghosts and devils. We are the living devils. The sign of life is strength and growth. The sign of death is weakness. Whatever is weak, avoid! It is death. If it is strength, go down into hell and get hold of it! There is salvation only for the brave. None but the brave deserves the fair. None but the bravest deserves salvation.
-Swami Vivekananda
