In the Disney movie Frozen, snowman Olaf desperately yearns for summer. And he dreams about all the lovely things he would do in summer. Like lazing on the beach with a drink in his hand, getting a suntan. Oh, and he can’t wait to see what his buddies will think of him. He is sure he will be so much cooler in summer.
He is not aware that he will melt.
That is a funny metaphor for the spiritual seeker who dreams about what enlightenment will do for him, but is not aware that the former familiar sense of self will be lost on the journey.

I have described the emotional effects of this melting process in my post about the Dark Night of the Soul.
