O sage, thus neither in childhood nor in youth nor in old age does one enjoy any happiness. None of the objects in this world is meant to give happiness to anyone. The mind vainly seeks to find such happiness in the objects of this world. Only he is happy who is free from egotism and who is not swayed by craving for sense-pleasure: but such a person is extremely rare in this world. Indeed, I do not regard him as a hero who is able to battle successfully against a mighty army; only him I consider a hero who is able to cross the ocean known as the mind and the senses.
RAMA continued: This world is like a potter's wheel: the wheel looks as if it stands still though it revolves at a terrific speed - even so to the deluded person this world appears to be stable even though in fact it is constantly changing. This world is like a poison tree: one who comes into contact with it is knocked unconscious and stupified. All points of view in this world are tainted; all countries in the world are territories of evil; all the people of the world are subject to death; all actions are deceitful.
(from Vasistha's Yoga, Swami Venkatesananda)
