A few years ago, a friend showed me one of the most beautiful tree drawings (there's also a psychological test, The Baum Test which involves this). It had one very strong and obvious characteristic: the branches were all directed towards the sky; not in a normal form, but almost like they were grabbing, craving for the sky.

We're doing something like this as well - we're yearning for spirituality, for freedom, we're yearning for the sky. It can have many different forms, but the sky is the best symbol for all. It's our ultimate goal, yet the one that we'll never reach as long as we're with the feet on the ground.
