The chief agency for keeping the blood pure is the air. When the blood returns to the lungs after one complete round over the body, it is impure and … - Mahatma Gandhi

Ours is not a drive for power, but purely a non-violent fight for India's independence. In a violent struggle, a successful general has been often known to effect a military coup and to set up a dictatorship.

A non-violent soldier of freedom will covet nothing for himself, he fights only for the freedom of his country.
I read Carlyle's French Revolution while I was in prison, and Pandit Jawaharlal has told me something about the Russian revolution. But it is my conviction that inasmuch as these struggles were fought with the weapon of violence they failed to realize the democratic ideal. In the democracy which I have envisaged, a democracy established by non-violence, there will be equal freedom for all. Everybody will be his own master. It is to join a struggle for such democracy that I invite you today. Once you realize this you will forget the differences between the Hindus and Muslims, and think of yourselves as Indians only, engaged in the common struggle for independence. We cannot evoke the true spirit of sacrifice and valour, so long as we are not free. I know the British Government will not be able to withhold freedom from us, when we have made enough self-sacrifice. We must, therefore, purge ourselves of hatred.

Walking gives movement to every portion of the body, and ensures vigorous circulation of the blood; for, when we walk fast, fresh air is inhaled into the lungs. Then there is the inestimable joy that natural objects give us, the joy that comes from a contemplation of the beauties of nature. ... Let those who are suffering from indigestion and kindred diseases try for themselves, and they will at once realise the value of walking as an exercise. (Chapter VII, Exercise)

Interdependence is and ought to be as much the ideal of man as self-sufficiency. Man is a social being. Without interrelation with society he cannot realize his oneness with the universe or suppress his egotism. His social interdependence enables him to test his faith and to prove himself on the touchstone of reality.
