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.
Mind you, this is life's experience: if you really want the good of others, the whole universe may stand against you and cannot hurt you. It must crumble before your power of the Lord Himself in you if you are sincere and really unselfish.
-Swami Vivekananda
