The Book of Zohar, Chapter “Mishpatim (Ordinances),” Item 343: He [King Solomon] signed his chair with a seal engraved with the holy Name, took a ring on which the holy Name was engraved, went on an ascent, riding that eagle, and went away.
Question: What is this ring?
Answer: This is a special force protecting Malchut, which restricts itself in order to use the Light of Hochma only from above downwards, above the will to enjoy, meaning in the intention to bestow rather than to receive into itself, into its egoistic desire. This is called a “ring.”
This is the origin of the wedding ritual where people put rings on each other, symbolizing their bestowal to one another and their connection.
