Mahatma Gandhi's One of Last Social Thought: How To Melt "Your Doubts and Your Self"! (1948)

"I will give you a talisman. Whenever you are in doubt, or when the self becomes too much with you, apply the following test. 

Recall the face of the poorest, and the weakest man, or a woman, whom you may have seen, and then ask yourself;

• If the step you're contemplating will be of any use to him or her. 
• Will he or she gain anything by it? 
• Will it restore his or her control over his or her own life and destiny? 
• In other words, will it lead to freedom for the hungry and spiritually starving millions?

Then you will find that "your Doubts and your Self" shall melt away."

*One of the last notes left behind by Gandhi in 1948, expressing his deepest social thought.
