The mind is the source of happiness and unhappiness by what it chooses to compare the experience with. If it chooses to compare it to something worse then it will create happiness, gratitude and pride but if it chooses to compare it to something better then it will create unhappiness, bitterness and envy.
Gautama BuddhaIf a man who enjoys a lesser happiness beholds a greater one, let him leave aside the lesser to gain the greater.
Gautama BuddhaImagine that every person in the world is enlightened but you. They are all your teachers, each doing just the right things to help you learn perfect patience, perfect wisdom, perfect compassion.
Gautama BuddhaLive happily, not hating even those who are hostile. Live peacefully even amongst those that hate.
Gautama Buddha
