Let go the past, let go the future, and let go the present (front, back, middle). Crossing to the farther shore of existence, with mind released everywhere, do not further undergo birth and decay.
Gautama BuddhaThe 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 Buddha
