Honesty means being the same inside out. Honesty with oneself helps one to bring about constant improvement in the self. Honesty with others enables one to relate positively under all circumstances. There is no rudeness but there is an openness that brings about love towards the other person.
When I am honest, I am able to experience progress in my own life and others are benefited too with my own self-progress. I am able to maintain harmony in my relationship with others because I am open with them and I find myself successful in my relationships.
