Answer: It is possible to add a spiritual component between husband and wife only when they understand what they are doing and why they exist.
They must realize that they have a unique opportunity to conduct themselves in all situations in life in such a way that they train on each other in mutual influence. Then they will be able to attain the revelation of the Creator, as it is written: “A husband and wife have, the Shechina between them.”
But only if they really are serious about achieving that goal. Because they must “step on themselves” and help each other.
