“Eternity is a long time, especially towards the end.”

The Tragic Sense of Life (1913), X : Religion, the Mythology of the Beyond and the Apocatastasis

Episode 2, Chapter 13-14
The Power of Myth (1988)
Context: Campbell: Eternity isn't some later time. Eternity isn't a long time. Eternity has nothing to do with time. Eternity is that dimension of here and now which thinking and time cuts out. This is it. And if you don't get it here, you won't get it anywhere. And the experience of eternity right here and now is the function of life. There's a wonderful formula that the Buddhists have for the Bodhisattva, the one whose being (sattva) is illumination (bodhi), who realizes his identity with eternity and at the same time his participation in time. And the attitude is not to withdraw from the world when you realize how horrible it is, but to realize that this horror is simply the foreground of a wonder and to come back and participate in it. "All life is sorrowful" is the first Buddhist saying, and it is. It wouldn't be life if there were not temporality involved which is sorrow. Loss, loss, loss.
Moyers: That's a pessimistic note.
Campbell: Well, you have to say yes to it, you have to say it's great this way. It's the way God intended it.

Context: Sex can be defined fairly adequately in physiological terms as consisting of the building up of bodily tensions and their release. Eros, in contrast, is the experiencing of the personal intentions and meaning of the act. Whereas sex is a rhythm of stimulus and response, eros is a state of being. The pleasure of sex is described by Freud and others as the reduction of tension; in eros, on the contrary, we wish not to be released from the excitement but rather to hang on to it, to bask in it, and even to increase it. The end toward which sex points is gratification and relaxation, whereas eros is a desiring, longing, a forever reaching out, seeking to expand.

Context: I have existed from all eternity and, behold, I am here; and I shall exist till the end of time, for my being has no end.
I soared into limitless space and took wing in the imaginal world, approaching the circle of exalted light; and here I am now, mired in matter.
I listened to the teachings of Confucius, imbibed the wisdom of Brahma, and sat beside Buddha beneath the tree of insight. And now I am here, wrestling with ignorance and unbelief. I was on Sinai when Yahweh shed his effulgence on Moses; at the River Jordan I witnessed the miracles of the Nazarene; and in Medina I heard the words of the Messenger to the Arabs. And here I am now, a captive of confusion.
