LEV26 Put salt on offerings. For the sake of rectifying the soul of the person who brings the offering, Hashem commands that offerings be of things that people value and enjoy, which includes that they have a pleasant and appealing taste. On animal offerings there must be salt, for meat without salt is much less tasty. If meat placed on the Altar as an offering is just as tasty as meat that people eat, the owner's heart and soul will be more influenced than if the meat is less tasty. Salt alludes to another matter. Just as salt, a preservative, keeps meat and other foods from spoiling and being destroyed, bringing an offering preserves one’s soul and enables it to live on forever.
