A feeling and a leaf
A leaf is to the tree, what the tree is to the forest, the forest is to the environment, the environment is to the ecosystem, the ecosystem is to the continent, and what the continent is to the earth.
Man's feelings are to his heart,
what the heart is to his emotions,
his emotions are to the soul, the soul is to humanity, humanity is to the forces of the universe, and what the forces of the universe are to God.
