"The first sign of this, was in church, I would just start crying while singing hymns. Then I would cry at my other meetings where we would close with a prayer. Everywhere I went suddenly I would just start crying - when I saw a beautiful sunset or a flower - Nature made me cry, singing made me cry, praying made me cry..."

Tiphareth means 'beauty' in Hebrew, so it is what happens when one is overwhelmed with the beauty of manifest existence that our soul is able express itself in our bodies in ways that effect our physiology.
