Soups are a creative enterprise and their benefit to our health is well documented. Not the processed kind full of sodium, but those made in a pot with fresh ingredients and cooked with care and time. You would never put vinegar in a good soup as it would be ruined, right?
Now, imagine creating and maintaining your relationships with others in the same way. Vinegar in relationships is self centeredness, deceit, violence, exploitation and a general lack of self control. Examine your inner goals. Learn what you need to do to succeed. Take care of yourself, and those with whom you relate, and you will build a more stable and satisfying life.
