“I answer, the man who regards his own life and that of his fellow creatures as meaningless is not merely unfortunate but almost disqualified for life.”

Context: We grudge no man a fortune which represents his own power and sagacity, when exercised with entire regard to the welfare of his fellows. Again, comrades over there, take the lesson from your own experience. Not only did you not grudge, but you gloried in the promotion of the great generals who gained their promotion by leading their army to victory. So it is with us. We grudge no man a fortune in civil life if it is honorably obtained and well used. It is not even enough that it should have been gained without doing damage to the community. We should permit it to be gained only so long as the gaining represents benefit to the community.

1920s, An Autobiography (1927)
Context: To see the universal and all-pervading Spirit of Truth face to face one must be able to love the meanest of creation as oneself. And a man who aspires after that cannot afford to keep out of any field of life. That is why my devotion to Truth has drawn me into the field of politics; and I can say without the slightest hesitation, and yet in all humility, that those who say that religion has nothing to do with politics do not know what religion means.
Identification with everything that lives is impossible without self-purification; without self-purification the observance of the law of Ahimsa must remain an empty dream; God can never be realized by one who is not pure of heart. Self-purification therefore must mean purification in all the walks of life. And purification being highly infectious, purification of oneself necessarily leads to the purification of one's surroundings.
But the path of self-purification is hard and steep. To attain to perfect purity one has to become absolutely passion-free in thought, speech and action; to rise above the opposing currents of love and hatred, attachment and repulsion. I know that I have not in me as yet that triple purity, in spite of constant ceaseless striving for it. That is why the world's praise fails to move me, indeed it very often stings me. To conquer the subtle passions seems to me to be far harder than the physical conquest of the world by the force of arms. Ever since my return to India I have had experiences of the dormant passions lying hidden within me. The knowledge of them has made me feel humiliated though not defeated. The experiences and experiments have sustained me and given me great joy. But I know that I have still before me a difficult path to traverse. I must reduce myself to zero. So long as a man does not of his own free will put himself last among his fellow creatures, there is no salvation for him. Ahimsa is the farthest limit of humility.

Context: Only a few years ago there was a great awakening of the human mind. Men began to inquire by what right a crowned robber made them work for him? The man who asked this question was called a traitor. Others asked by what right does a robed hypocrite rule my thought? Such men were called infidels. The priest said, and the king said, where is this spirit of investigation to stop? They said then and they say now, that it is dangerous for man to be free. I deny it. Out on the intellectual sea there is room enough for every sail. In the intellectual air there is space enough for every wing.
The man who does not do his own thinking is a slave, and is a traitor to himself and to his fellow-men.

Context: Wild animals never kill for sport. Man is the only one to whom the torture and death of his fellow creatures is amusing in itself.
