“God speaks only in the suffering of creatures, a suffering that the hearts of the unbelievers do not have because they become more and more hardened.”

Love is not a feeling ~ The Article (1995)
Context: In other words, to be enlightened of the acquired burden every spiritual belief and notion has to be abandoned, every reference to what any spiritual teacher or master has ever said must be set aside. What does that leave? Your own experience. Not your historical or memorable experience, for that's the problem. Your own experience is your self-knowledge of life. Let's establish once and for all what this means now. Forget everything I've said in this article except this question: Do I want to suffer or not suffer NOW? That's the only truth for you. There's no tradition, no past, no discussion in it. It's all you need. Keep it with you and at the next temptation to suffer it will prevent you suffering. But only if you've learned in your own experience what causes you to suffer. If you haven't learned that, you're still attached to suffering and will unwittingly embrace it. In that case you have to read on, take more time and ask yourself more questions.

Context: Indeed, the truth that many people never understand, until it is too late, is that the more you try to avoid suffering, the more you suffer, because smaller and more insignificant things begin to torture you, in proportion to your fear of being hurt. The one who does most to avoid suffering is, in the end, the one who suffers the most: and his suffering comes to him from things so little and so trivial that one can say that it is no longer objective at all. It is his own existence, his own being, that is at once the subject and the source of his pain, and his very existence and consciousness is his greatest torture.

Context: Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.
The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.
Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower.
