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 brave! Be strong! Be fearless! Once you have taken up the spiritual life, fight as long as there is any life in you. Even though you know you are going to be killed, fight till you are killed. Don't die of fright. Die fighting. Don't go down till you are knocked down.
-Swami Vivekananda
