Physical objects in our everyday world can be manifestations of their spiritual essence, just as Spiritual belief, divorced from the tangible world, can be naive. Consider the happiness of bringing a creative idea from the world of spirit into the world of matter.
We are not the source of generosity and fruitful acts, but we can be the vessels through which these virtues flow upon others. Unconditional love expresses in actual service. We build our earthly and spiritual lives by the state of our consciousness. And we create our consciousness in that balance - just as gravity acts on a pendulum's swing, and the droplets of mist are transformed with the sunlight into the rainbow.
