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 BuddhaWell-makers lead the water (wherever they like) ; fletchers bend the arrow ; carpenters bend a log of wood ; wise people fashion themselves.
