Before practicing a betrayal, do not think only of yourself and not only the consequences that will bring to the present relationship. Ponder what this unfaithful attitude will unleash in the future for that other person, for besides the pain of betrayal, of losing the one you love (the victim of betrayal sees it almost with a death), and that separation will leave the sequels. This book is intended to guide people to avoid or overcome 'horns'. Never again will someone betray you, but if someone betrays you you will know how to overcome the pain of betrayal. The Corna is the holy book of the horns.
