“Are we, in blind obedience to primitive instincts and old prejudices, enslaved by the old catchwords and that curious indolence which makes the revision of old ideas unpleasant, to duplicate indefinitely on the political and economic side a condition from which we have liberated ourselves on the religious side? Are we to continue to struggle, as so many good men struggled in the first dozen centuries of Christendom — spilling oceans of blood, wasting mountains of treasure — to achieve what is at bottom a logical absurdity, to accomplish something which, when accomplished, can avail us nothing, and which, if it could avail us anything, would condemn the nations of the world to never-ending bloodshed and the constant defeat of all those aims which men, in their sober hours, know to be alone worthy of sustained endeavor?”

General sources
Context: By the time we awaken faintly to the awareness that we have been socially conditioned, we find ourselves so indoctrinated that it's difficult, if not impossible, to break the old patterns … Survival pressures demanding that we evolve, grow, and change, however, continue to proliferate. We don't want to change, but the floodgates open abruptly and we are overwhelmed.
Crisis!

Introducing "Who by Fire"
Warsaw concert (1985)
Context: I come from a country where we do not have the same struggles as you have. I respect your struggles. And it may surprise you, but I respect both sides of this struggle. It seems to be that in Europe there needs to be a left foot and a right foot to move forward. I wish that both feet move forward and the body moves towards its proper destiny. This is an intense country; the people are heroic, the spirit is independent. It is a difficult country to govern, it needs a strong government and a strong union. … I would like to say to you, to the leaders of the left, and the leaders of the right, I sing... I sing for everyone. My song has no flag, my song has no party. And I say the prayer, that we said in our synagogue, I say it for the leader of your union and the leader of your party. May the Lord put a spirit, a wisdom and understanding into the hearts of your leaders and into the hearts of all their counsellors.

The Saviors of God (1923)
Context: We do not struggle for ourselves, nor for our race, not even for humanity.
We do not struggle for Earth, nor for ideas. All these are the precious yet provisional stairs of our ascending God, and they crumble away as soon as he steps upon them in his ascent.
In the smallest lightning flash of our lives, we feel all of God treading upon us, and suddenly we understand: if we all desire it intensely, if we organize all the visible and invisible powers of earth and fling them upward, if we all battle together like fellow combatants eternally vigilant — then the Universe might possibly be saved.
It is not God who will save us — it is we who will save God, by battling, by creating, and by transmuting matter into spirit.
