Nature of rain

Does rain happen for a reason? And was meaning of rain given by rain itself or man? Something that ran through my mind when I was mugging at somewhere watching the rain....

Common observation would be the rain falls naturally and spontaneously with no reason. But as I look deeper. Rain is the result of water vapour, heat and wind. Missing one of the factor, there is no rain.

Does rain fall for a reason? Then, who gives it reason? Why is there rain? With rain, there is life. So is it god's gift to life on earth? But if its god-sent, with his omnipotent power, life need not depend on rain.

And if it is not god-sent, who else gives it meaning? Poet? Poems and stories indeed paint an even more significant role of rain then just supporting life. Yet, if someone has the ability to control rain, then he is not doing a good job in giving timely rain causing floods and drought.

Maybe by transcending the concepts of duality can man understand the meaning of rain, the nature of life.

All credits goes to the buddhism chants I am listening, bible at the next table, and the nice shelter under the rain :P
