“It’s precisely because of the pain, the we can get the feeling, through this process, of really being alive—or at least a partial sense of it.”

Context: “Humanity has evolved—as far as it has evolved,” continued the old priest, “with no thanks to its predecessors or itself. Evolution brings human beings. Human beings, through a long and painful process, bring humanity.”
“Empathy,” Aenea said softly.

Essay as "Mr. X" (1969)
Context: I do not consider myself a religious person in the usual sense, but there is a religious aspect to some highs. The heightened sensitivity in all areas gives me a feeling of communion with my surroundings, both animate and inanimate. Sometimes a kind of existential perception of the absurd comes over me and I see with awful certainty the hypocrisies and posturing of myself and my fellow men. And at other times, there is a different sense of the absurd, a playful and whimsical awareness. Both of these senses of the absurd can be communicated, and some of the most rewarding highs I've had have been in sharing talk and perceptions and humor. Cannabis brings us an awareness that we spend a lifetime being trained to overlook and forget and put out of our minds. A sense of what the world is really like can be maddening; cannabis has brought me some feelings for what it is like to be crazy, and how we use that word "crazy" to avoid thinking about things that are too painful for us. In the Soviet Union political dissidents are routinely placed in insane asylums. The same kind of thing, a little more subtle perhaps, occurs here: "did you hear what Lenny Bruce said yesterday? He must be crazy."

Dichoso el árbol, que es apenas sensitivo,
y más la piedra dura porque esa ya no siente,
pues no hay dolor más grande que el dolor de ser vivo,
ni mayor pesadumbre que la vida consciente.

It can really hurt

To give these moments back
To those we love
To those who will survive…</p

Finding Life after Death http://richardcarlson.com/RC_Words/life_after_death.html
What About the Big Stuff (2002)
Context: When our familiar world falls apart, especially through the pain of death — of losing someone we love — we are shaken at our very core. We realize, perhaps for the first time, that there is no easy or quick way out. We must go through the process, which will be a little different for each of us — the common thread being pain.
In the midst of that inner struggle, however, something begins to happen. There are the moments that are most resisted — and there is extreme pain. Simultaneously, however, there are voluntary or involuntary bursts of letting go. Perhaps the pain is too much for the moment — the mind takes a break, shuts down, or wakes up, I’m not really sure. But in those moments, there is a release from the pain; an acknowledgment that although we don’t understand it, and it hurts like hell, the universe somehow knows what it’s doing.
