If you watch a tree during a storm, and you focus only on the swaying branches and leaves, you are sure it could break.

If you focus on the trunk however, you will see the power and strength and know it will not fall.  The leaves and swaying branches are chaos.  The trunk is the polar opposite.  And yet they work together.  The trunk and its roots cannot be without the nourishment it receives from the leaves.  The leaves and branches cannot survive without the stability from the trunk and the nourishment received from the water, coming from the roots.

Man and woman. Joy and pain. Sunshine and rain. It is light and dark. One cannot exist without the other.

The symbolism of trees and leaves is apparent in common metaphors such as the Tree of Life, our ancestral heritage depicted in ‘family trees’, how we ‘put down roots’ when we create lasting relationships, and in the phrase ‘turning over a new leaf’ when we experience significant change for the better. Trees and leaves are ubiquitous in the fabric of our lives.

The term silver lining is the hopeful side of a situation that might seem gloomy on the surface.  The common expression "every cloud has a silver lining" means that even the worst events or situations have some positive aspect.
