The seed is put in the ground, and earth and air and water are placed around it. Does the seed become the earth, or the air, or the water? No. It becomes a plant, it develops after the law of its own growth, assimilates the air, the earth, and the water, converts them into plant substance and grows into a plant.
Similarly each one of us must assimilate the spirit of the others and yet preserve our individuality and grow according to our own law of growth.
