"...Excess sorrow laughs, Excess joy Weeps..."
(been re-reading Blake)
There is a subtle difference between experiencing emotions and attaching ourselves to those emotions. Part of the gig is the forward push to the evolution of our being (as you point out). The other part is the arcade, the ride of life, the throwing up of the arms on the rollercoaster's plunge. Even the gods come here to play.
When you are in the meta-physical disneyland, it's okay to laugh your ass off, and enjoy the resulting tears.
Isn't that why ole J.C. decided to incarnate? Or the immortals keep getting a fistfull of "E" tickets?
Found a word the other day I rather like:
"perfruor"
(dibs on that as a screen name!)
Enjoy your day. It's okay.
