Hi Pratibha!
I've experienced so many serendipities in my life that when I suddenly find someone today who has an insight concerning the power of concentration and the "conscious" mind, which is quite similar to mine, I am not so surprised. I agree with you, Pratibha, concerning the potential found in developing concentration. I, too, think that if there is only one aspect of myself that I can and should improve and develop, it should be concentration. The key to success in most(or maybe in ALL)human endeavours is concentration. But I also believe in balance. Concentration and balance should go hand in hand. One should balance developing one's mind's ability to concentrate and to be "free, receptive and open" to ideas, random images(etc). Even when one endeavours to be in the latter state of mind("open, receptive"..), one must CONCENTRATE(forgive the caps) on one's inflowing stream of images, random ideas etc. On the other side of the coin, when one attempts to concentrate on an inward or outward object, one should be OPEN and RECEPTIVE to the object of concentration, so as to let the object fill your consciousness, without you forcing it. Ahh.. whenever I come across these truths, I wonder at the beauty and complexity of the workings of Man, Mind and Universe, all being creations of God.
