Suffering comes from three quarters: from our own body, which is destined to decay and dissolution, and cannot even dispense with anxiety and pain as danger-signals; from the outer world, which can rage against us with the most powerful and pitiless forces of destruction; and finally from our relations with other men.

We are the cause of our own sufferings.

One of those realizations was this: that life itself is a form of suffering. The rich suffer because of their riches. The poor suffer because of their poverty. People without a family suffer because they have no family. People with a family suffer because of their family. People who pursue worldly pleasures suffer because of their worldly pleasures. People who abstain from worldly pleasures suffer because of their abstention.
This isn’t to say that all suffering is equal. Some suffering is certainly more painful than other suffering. But we all must suffer nonetheless.

Deep in our unconscious, we believe that we have hopelessly defiled our original innocence, that we “have made a devil of God’s Son.”8 This belief is the hidden cause of all our suffering, for it is a constant affirmation that we deserve to suffer, as punishment for what we’ve done.

We suffer but little from suffering itself; but from the manner wherein we accept it overwhelming sorrow may spring.

We are wrong in believing that it comes from without. For indeed we create it within us, out of our very substance.

Perhaps we are no longer a kind people. More and more, we seem to have become numb to the suffering of others and ashamed of our own suffering. Yet suffering is one of the universal conditions of being alive. We all suffer. We have become terribly vulnerable, not because we suffer but because we have separated ourselves from each other.

All human suffering is a variation on this theme — trying to control the waves, trying to control our present-moment experience so it conforms to our ideas and concepts of how it should be. If you want to suffer, compare this moment with your image of how it should be! I

What is the source of our first suffering? It lies in the fact that we hesitated to speak....it was born in the moments when we accumulated silent things within us.

If there is meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death. Without suffering and death human life cannot be complete.

It’s not impermanence per se, or even knowing we’re going to die, that is the cause of our suffering, the Buddha taught. Rather, it’s our resistance to the fundamental uncertainty of our situation. Our discomfort arises from all of our efforts to put ground under our feet, to realize our dream of constant okayness. When we resist change, it’s called suffering. But when we can completely let go and not struggle against it, when we can embrace the groundlessness of our situation and relax into its dynamic quality, that’s called enlightenment, or awakening to our true nature, to our fundamental goodness. Another word for that is freedom — freedom from struggling against the fundamental ambiguity of being human.

All suffering is caused by my identifying myself with something, whether that something is within me or outside of me.

All suffering originates from craving, from attachment, from desire.

The root of suffering is resisting the certainty that no matter what the circumstances, uncertainty is all we truly have.

This truth of suffering guides you inward and makes you wonder where the suffering begins; with proper insight it will point you to your own mental reactions. The truth of suffering may seem overwhelming and unavoidable, but it reflects your own power — it highlights the potential for real freedom and happiness.
