Indian Opinion (1 October 1903)
1900s
Context: One thing we have endeavoured to observe most scrupulously, namely, never to depart from the strictest facts and, in dealing with the difficult questions that have arisen during the year, we hope that we have used the utmost moderation possible under the circumstances. Our duty is very simple and plain. We want to serve the community, and in our own humble way to serve the Empire. We believe in the righteousness of the cause, which it is our privilege to espouse. We have an abiding faith in the mercy of the Almighty God, and we have firm faith in the British Constitution. That being so, we should fail in our duty if we wrote anything with a view to hurt. Facts we would always place before our readers, whether they are palatable or not, and it is by placing them constantly before the public in their nakedness that the misunderstanding between the two communities in South Africa can be removed.

Context: One rule observed in their council is, never to debate a thing on the same day in which it is first proposed; for that is always referred to the next meeting, that so men may not rashly and in the heat of discourse engage themselves too soon, which might bias them so much that, instead of consulting the good of the public, they might rather study to support their first opinions, and by a perverse and preposterous sort of shame hazard their country rather than endanger their own reputation, or venture the being suspected to have wanted foresight in the expedients that they at first proposed; and therefore, to prevent this, they take care that they may rather be deliberate than sudden in their motions.

Saanen, Switzerland (5 August 1973)
1970s
Context: Now, one sees all that by observing, by being aware, watching, one is aware of all this. Then out of that awareness you see there is no division between the observer and the observed. It is a trick of thought which demands security. Please don't madam, please. And by being aware it sees the observer is the observed, that violence is the observer, violence is not different from the observer. Now how is the observer to end himself and not be violent? Have you understood my question so far? I think so. Right? The observer is the observed, there is no division and therefore no conflict. And is the observer then, knowing all the intricacies of naming, linguistically caught in the image of violence, what happens to that violence? If the observer is violent, can the observer end, otherwise violence will go on? Can the observer end himself, because he is violent? Or what reality has the observer? Right sir? Is he merely put together by words, by experience, by knowledge? So is he put together by the past? So is he the past? Right? Which means the mind is living in the past. Right? obviously. You are living in the past. Right? No? As long as there is an observer there must be living in the past, obviously. And all our life is based on the past, memories, knowledge, images, according to which you react, which is your conditioning, is the past. And living has become the living of the past in the present, modified in the future. That's all, as long as the observer is living. Now does the mind see this as a truth, as a reality, that all my life is living in the past? I may paint most abstract pictures, write the most modern poems, invent the most extraordinary machinery, but I am still living in the past.
