Can my altar face the dining table?
So long as the deity sitting on the altar: at EYE LEVEL does not DIRECTLY face the dining table TOP. If this "test" is passed; then no issue. Why not?
Standard off the shelf commercially purchased altars have specific altar heights of around 49 3/4 inches. This is the norm. If so, this much higher than a regular (normal) dining table other than those bar counter tops.
