The verse that surrounds the ketubah:
“From every human being there rises a light that reaches straight to heaven
and when two souls that are destined to be together find each other,
their streams of light flow together and a single brighter light goes forth from their united being” (Ba’al Shem Tov)

The Jewish mystical doctrine known as Kabbalah 
is distinguished by its theory of ten creative forces that intervene between the infinite, unknowable God (“Ein Sof”) and our created world.
Through these powers God created and rules the universe,
and it is by influencing them that humans cause God to send to Earth forces
of compassion (masculine, right side)
or severe judgment (feminine, left side).

here are 10 Sefirot, linked to the “Tree of Life”  
Each of them represents one aspect of the Godhead, a facet of the powers of the All Powerful. Each is also identified with a part of the body or aspects of the human personality, a color, and one of the Names of the Holy One.
