Response.

Why is it, that we cannot bear too much unhappiness? Because we are taught to experience as much happiness as possible. If one reacts to happiness, one reacts to unhappiness also. He/She, who can be self controlled in happiness, or that person, who does not go out looking for happiness, is most self controlled in unhappiness. How does one reach this state? By not identifying oneself as a personality, but by experiencing life, nonetheless, I believe. Unhappiness is nothing but disappointment, perhaps.
