One must rise above one's likes and dislikes, for they cause much weakness in life. When one says, "I cannot stand this, I cannot eat this, I cannot drink this, I cannot bear this, I cannot tolerate, I cannot endure" - all those things show man's weakness. The greater the will-power the more man is able to stand all that comes along. It does not mean that one has no choice; one can have one's choice, but when one gives in to one's choice then life becomes difficult. There is a false ego in man, called nab by the Sufis, and this ego feeds on weakness. This ego feels vain when one says, "I cannot bear it, I do not like it, I do not look at it." All this feeds the ego and its vanity. It then thinks, "I am better than others", and thereby this ego becomes strong, and so man's weakness becomes strong. But the one who has discrimination, distinction, choice, while at the same time having these all under his control, the one who enjoys sweet but can drink a bowl of something bitter,- that person has reached mastery.
