“The first lesson on Roke, and the last is, Do what is needful! And no more.”
“The lessons in between, then, must consist in learning what is needful.”
“They do.”

“In order for one to learn the important lessons of life, one must first overcome a fear each day.”

Speech to the Classical Association (8 January 1926), quoted in On England, and Other Addresses (1926), p. 107.
1926
Context: Believing as I do that much of the civilisation and culture of the world is bound up with the life of Western Europe, it is good for us to remember that we Western Europeans have been in historical times members together of a great Empire, and that we share in common, though in differing degrees, language, law, and tradition. That there should be wars between nations who learned their first lessons in citizenship from the same mother seems to me fratricidal insanity.

The Uttarpara Address (1909)
Context: I waited day and night for the voice of God within me, to know what He had to say to me, to learn what I had to do. In this seclusion the earliest realisation, the first lesson came to me. I remembered then that a month or more before my arrest, a call had come to me to put aside all activity, to go in seclusion and to look into myself, so that I might enter into closer communion with Him. I was weak and could not accept the call. My work was very dear to me and in the pride of my heart I thought that unless I was there, it would suffer or even fail and cease; therefore I would not leave it. It seemed to me that He spoke to me again and said, "The bonds you had not the strength to break, I have broken for you, because it is not my will nor was it ever my intention that that should continue. I have had another thing for you to do and it is for that I have brought you here, to teach you what you could not learn for yourself and to train you for my work." Then He placed the Gita in my hands. His strength entered into me and I was able to do the sadhana of the Gita. I was not only to understand intellectually but to realise what Sri Krishna demanded of Arjuna and what He demands of those who aspire to do His work, to be free from repulsion and desire, to do work for Him without the demand for fruit, to renounce self-will and become a passive and faithful instrument in His hands, to have an equal heart for high and low, friend and opponent, success and failure, yet not to do His work negligently. I realised what the Hindu religion meant. We speak often of the Hindu religion, of the Sanatan Dharma, but few of us really know what that religion is. Other religions are preponderatingly religions of faith and profession, but the Sanatan Dharma is life itself; it is a thing that has not so much to be believed as lived. This is the Dharma that for the salvation of humanity was cherished in the seclusion of this peninsula from of old. It is to give this religion that India is rising. She does not rise as other countries do, for self or when she is strong, to trample on the weak. She is rising to shed the eternal light entrusted to her over the world. India has always existed for humanity and not for herself and it is for humanity and not for herself that she must be great.
