Keats wrote in
Ode on a Grecian Urn (I prefer Chinese porcelain, actually
):
"Beauty is truth, truth beauty." -- that is all
Ye know on earth, and all ye need to know.
Make your life a pursuit of beautiful things -- not just in the narrow sense of the fine arts, but also in the more important sense of developing your inner beauty. That, for me, would suffice as the meaning of life. (You might also like to look at the Religion II thread started by Cerek.)
