Air is every where but we need fan to feel it. Its as simple as that.
Similarly, in life When we face any problems its only us who will have solution for every thing yet we need someone to make us realise what is the solution, how to find the solution. Without turning on the fan you may never enjoy the air blow and without seeking a help you may never understand the solution. It may be possible that you can take a decision without help however the shortest and the most preferable idea is to turn on the power and feel instant air.
However in contrast to this whole way of getting air from fan we can get natural air too. And by saying that I mean we need to keep our inner self calm and all you can feel is a calmness within, fresh and purified thoughts like the fresh and purified air.
It is always good keeping oneself calm and finding answers within rather searching for artificial air.
