Daleth
Looking like a door frame, the Daleth poses the question if we are the if we are going to open the door to our hopes and dreams or remain alienated and closed off. The bump on the top represents the humility we have when we enter into the house of God.
He
This letter makes the sound as “hay”. It represents the divine breath, revelation, and light. Interesting that it is the fifth letter and in Genesis 1:3-4, light is mentioned five times. It connects to the physical level with the five senses and the spiritual level the five levels of our soul — emotions, instincts, mind, oneness,and bridge to transcendence.
Vav
Represents the divine hook connecting heaven and earth. Being the sixth letter it is connected to man being created on the sixth day and works six days.
