Crying
Crying and laughter are deeply related. Whenever you are overwhelmed by something, either you cry or you laugh. Crying is not necessarily sad, laughter is not necessarily joyous. Sometimes crying is a joy, sometimes laughter is ugly and maybe just a device to hide your sadness.
Remember one thing: it is only man who can cry and laugh. No other animal can do it, because no other animal is conscious enough to feel overwhelmed. Only man has that much consciousness that he can feel overwhelmed, flooded with something so much that either he starts crying or he starts laughing—and both capacities are tremendously needed.
Crying will help you to relieve your tensions; laughter will help you to dance, to sing. Both are interlinked. Crying prepares the way for laughter: your tears will cleanse your heart, and then laughter will arise. If the first process has started the second is not far away.
