Nature
The emotion and rapture we feel from contemplating nature is a memory of a time when we were animals, trees, flowers, the earth. More precisely: it is a consciousness of unity with everything, hidden from us by time.
Architecture
When you see what great buildings people built in the old days, you can't help but think that they were happier than we are.
Sea
You see, all they talk about in heaven is the sea. How infinitely beautiful it is. About the sunset they saw. About how the sun, sinking into the waves, turned as scarlet as blood. And they felt that the sea had absorbed the energy of the luminary into itself, and the sun was tamed, and the fire was already burning out in the depths.
