The is like the ד but it has the rounded corner; it takes on and includes personality. The word means destitute. [v 1] It is why people fall on their faces when God reveals himself. They are destitute before him. When God walked with Adam, or met Moses on the mountaintop, these were experiences.
With a ד experience, you cannot ask questions; it is a command. With a ר experience you can dialog and know. Say "reveals, revealed, or revealing" when drawing the ר.
