weight vs lightness

"the heavier the burden, the closer our lives come to the earth, the more real and truthful they become. conversely, the absolute absence of a burden causes man to be lighter than air, to soar into the heights, take leave of the earth and his earthly being, and become only half real, his movements as free as they are insignificant. what then shall we choose? weight or lightness?"

i've just started to read a novel titled "the unbearable lightness of being," the above being an excerpt from it. i've been pondering this quote all day today, and i have yet to reach a conclusion. it's especially interesting to look at it from the Christian viewpoint.

the weight in some respects seems to be more desirable because of the reality and truth it brings. as Christians we believe that our burdens (or, weight) are given to us by God. therefore, acknowledging these acts of God, the heaviness might appear to be somewhat more attractive.

but then what about lightness? we are taught that Christ is the source of all light and all truth. and taking leave of the earth and man's earthy being keeps bringing up, in my mind, the thought of resurrection. our movements are free, just like our free will.

so, which is it?
