Service is one of the two main levers of evolution: one is meditation, the other is service. Service, of whatever kind, gradually distances you from yourself. As your service grows, expands outwards from yourself, you do not lose touch with yourself but you become less and less concerned with your own ego, your personality expression. Service is the impulse of the soul, the carying out of soul purpose.
The oak tree in full foliage praises the Creator, but in order to become the oak tree, the acorn has to open in the dark. Its roots have to reach deep into the earth as its branches stretch toward the light. There in the dark the shell has to crack. Only when I let go of my protective shell, when I find the crack makes me vulnerable, that opens me to the Other, only then will the night be radiant, only then will the dark be light... The spark is in everyone's soul: the spark of our Creator shining in the dark. This spark is ours to tend, to take care of until it flares into a brilliant flame, lit by God.
