be like a child!

so often we find inspirational and spiritual gurus talking about "child-like" qualities being the best way of life. to always smile and laugh freely and be happy without many terms and conditions to oneself. but sometime i wonder why they miss out an important aspect of the same phenomenon. To be child-like and free of burden is not only about laughing spontaneously: its also equally about crying spontaneously. A child does not bottle up its emotions for the sake of appearing to be strong. Why then, this indifference towards how we perceive child-like innocent qualities! Life does not guarantee happiness always. So instead of making an effort to be able to just laugh naturally, we must also endeavour to cry naturally like a child if the situation demands so. Perhaps that could later help to multiply our reasons to smile more! :)
