Desire is the seed of all fear and sorrow. The root of ‘samsara’ is desire.
Worldly desires are of the nature of bondage, they are also its cause, tying down a man with no visible chain, he cannot go beyond the end of tether. Yet he is proud of his freedom.
The first thing that true seekers of happiness have to do is to conquer desire.
It is impossible to exhaust desires though enjoyment. So the only way to overcome them is through right thinking.
