Politics is conflict
You want to do something to prevent, to bring about the cessation of, the starvation in this country. Then what happens? You join the socialist, the communist, or the capitalist movement; you are caught in that; you will become a member of the party, and you will always postpone doing something about starvation. Then, what are you to do? If you join a party, socialist or communist, what happens? Each party wants to solve poverty, starvation, according to its ideas, according to its patterns; and so each party wants to start from its pattern. So, the two parties are at war with each other, and the poor chap in the meantime is hungry everlastingly. So, what is one to do?
The Collected Works of J. Krishnamurti -Volume XIV 1963-1964: The New Mind
Jiddu Krishnamurti

It is essential to free the mind from political systems (J. Krishnamurti)
You may superficially agree when you hear it said that nationalism, with all its emotionalism and vested interest, leads to exploitation and the setting of man against man; but to really free your mind from the pettiness of nationalism is another matter. To be free, not only from nationalism but also from all the conclusions of organized religions and political systems, is essential if the mind is to be young, fresh, innocent, that is, in a state of revolution; and it is only such a mind that can create a new world, not the politicians, who are dead, nor the priests, who are caught in their own religious systems.
So, fortunately or unfortunately for yourself, you have heard something which is true; and if you merely hear it and are not actively disturbed so that your mind begins to free itself from all the things which are making it narrow and crooked, then the truth you have heard will become a poison. Surely, truth becomes a poison if it is heard and does not act in the mind, like the festering of a wound. But to discover for oneself what is true and what is false, and to see the truth in the false, is to let that truth operate and bring forth its own action.
J. Krishnamurti, The Book of Life

Politics is always in conflict
“The unity of man can never be brought about through legislation, however enlightened.”

“A truly religious man is not concerned with politics; to him there is only action, a total religious action, and not the fragmentary activities which are called political and social.” 230
“Can politics ever be spiritualized? Politics are concerned with society, which is always in conflict with itself, always deteriorating. The interrelationship of human beings constitutes society, and that relationship is actually based on ambition, frustration, envy. Society knows no compassion. Compassion is the act of a total and integrated individual.” 231
“There may be a semblance of unity, the outward following of a universal pattern, social or political, but the unity of man can never be brought about through legislation, however enlightened. Where there’s friendship, compassion, the organization of justice is unnecessary; and through the organization of justice, compassion does not necessarily come into being. On the contrary, it may banish compassion.” 231

"Can I act politically to help bring about such a revolution?"
If one may ask, what do you mean when you talk about acting politically? Is political action, whatever that may be, separate from the total action of man, or is it part of it? "By political action, I mean action at the governmental level: legislative, economic administrative, and so on."
Surely, if political action is separate from the total action of man, if it does not take into consideration his whole being, his psychological as well as his physical state, then it is mischievous, bringing further confusion and misery; and this is exactly what is taking place in the world at the present time. Cannot man, with all his problems, act as a complete human being, and not as a political entity, separated from his psychological or 'spiritual' state? A tree is the root, the trunk, the branch, the leaf and the flower. Any action which is not comprehensive, total, must inevitably lead to sorrow. There is only total human action, not political action, religious action, or Indian action. Action which is separative, fragmentary, always leads to conflict both within and without.
"This means that political action is impossible, doesn't it?"
Not at all. The comprehension of total action surely does not prevent political, educational or religious activity. These are not separate activities, they are all part of a unitary process which will express itself in different directions. What is important is this unitary process, and not a separate political action, however apparently beneficial. "I think I see what you mean. If I have this total understanding of man, or of myself, my attention may be turned in different directions, as necessary, but all my actions will be in direct relation to the whole. Action which is separative, departmentalized can only produce chaotic results, as I am beginning to realize. Seeing all this, not as a politician, but as a human being, my outlook on life utterly changes; I am no longer of any country, of any party, of any particular religion. I need to know God, as I need to have food, clothing and shelter; but if I seek the one apart from the other, my search will only lead to various forms of disaster and confusion. Yes, I see this is so. politics, religion and education are all intimately related to each other.
