Noble behavior means behaving in a most friendly and most cordial manner. Behavior includes your thought, speech, and action. If this triple mode of expression of your behavior is contradictory, your behavior cannot be noble behavior. Our noble thought will one day express itself in noble behavior and our spiteful thought in evil behavior. Remember that your thoughts are transformed into speech and action in order to bring the expected result.
Thought translated into action is capable of producing tangible result.
You should always speak and do things with mindfulness of loving-kindness. While speaking of loving-kindness, if you act or speak in a diametrically opposite way you will be reproached by the wise. As mindfulness of loving-kindness develops, your thoughts, words and deeds should be gentle, pleasant, meaningful, truthful and beneficial to you as well as to others. If your thoughts, words or deeds cause harm to you, to others or to both, then you must ask yourself whether you are really mindful of loving-kindness. For all practical purposes, if all of your enemies were well, happy and peaceful, they would not be your enemies.
