After too much pondering of deep, religious issues, my mind needs a break. At these moments I turn to beauty, especially feminine beauty.
The following photo, via Classic Porn: http://classicporn.tumblr.com/ is nice. It is sensual, sexual, without being lewd or crass. She has a somewhat exotic look, or perhaps it is a more southern Mediterranean look (I have always found Spanish women to be quite beautiful: the dark hair, dark eyes, hot temper). It is a wonderful expression of beauty. When the mind is weary from so many philosophical lucubrations, such an image or pure earthiness delights and relaxes.
