The four catagories of existance, non-existance, both existance and non-existance, and neither existance nor non-existance, are spiderwebs among spiderwebs which can never take hold of the enormous bird of reality
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
