They are indeed wise, who know that the secret of success is concentration. Concentration is essential for every person whatever his vocation may be. A businessman, a barber, a blacksmith, a student or a teacher, all of them need concentration to succeed in their professions. By concentration we mean, the concentration of mind. The mind which Sri Krishna regarded as most restless than any other thing in Bhagvad Gita. It is very surprising to know that 90 % of the thought force is wasted by an ordinary human being in irrelevant and unnecessary things. Hence, whatever we have achieved is the results of 10 % of the thought force which we could able to utilize. What if our mind is utilized up to 100 %? If we look into past history, we would find that no great discovery has been ever made without concentrating the mind on a subject. Therefore, it becomes very important to understand the power of concentration.

Not all are aware that the sun’s rays have the power to ignite fire. Why don’t they know? The reason is, they would not have seen the sun’s rays creating fire and burning down things! But when the same rays are passed through a convex lens and made to fall on a piece of paper, they can burn the paper. How did the rays acquire this power? It was the result of making them converge and thereby, ’concentrated’. Our mind is also very similar to a shining sun which can produce fire provided its energies are concentrated and directed towards a single point.
Swami Vivekananda had also emphasized on concentrating the mind which is reflected in his following quote,
The old idea was: ’Develop one idea at the expense of all the rest’. The modern way is ’harmonious development’. A third way is to ’develop the mind and control it’, then put it where you will; the result will come quickly. This is developing yourself in truest way. Learn concentration and use it in any direction. Thus you lose nothing. He who gets the whole must have the parts too.

Let me further explain the power of concentration with few more examples. A well known story about Arjuna exemplifies his powers of concentration. Once Guru Dronacharya decided to test his students in their skill of archery. He hung a wooden bird from the branch of a tree and then summoned his students. He asked the first one to aim for the bird’s eye but not shoot just yet. He then asked the student what the student could see. The student replied that he could see the garden, the tree, flowers, etc. Drona asked him to step aside and not shoot. He repeated the same process with a few other students. When it was Arjuna’s turn, Arjuna told his Guru that the only thing he could see was the bird’s eye. This satisfied the Guru and he allowed Arjuna to shoot the bird. The lesson here is the power of focus. It was the power of concentration which made him a peerless archer.
In continuation, we come across Dhruv who is known as ’parama-udharan’ of such determination and concentration. He armoured the lord Sri Krishna himself with his power of concentration and devotion. Sri Krishna after being pleased turned him into a little star and placed him high in the sky, above the world, and away from all jealousy and evil. Even today, when we look up into the sky, we will be able to see a little star shining high above. This little star never moves, for it is Dhruv, who never moved from his meditation of Narayan.
There is an another story which demonstrates the importance of concentration while mastering an art. After winning several archery contests, one young and rather boastful champion challenged a Zen master who was renowned for his skill as an archer. The young man demonstrated remarkable technical proficiency when he hit a distant bull’s eye on his first try, and then split that arrow with his second shot. ”There,” he said to the old man, ”see if you can match that!” Undisturbed, the master did not draw his bow, but rather motioned for the young archer to follow him up the mountain. Curious about the old fellow’s intentions, the champion followed him high into the mountain until they reached a deep chasm spanned by a rather flimsy and shaky log. Calmly stepping out onto the middle of the unsteady and certainly perilous bridge, the old master picked a far away tree as a target, drew his bow, and fired a clean, direct hit. ”Now it is your turn,” he said as he gracefully stepped back onto the safe ground. Staring with terror into the seemingly bottomless and beckoning abyss, the young man could not force himself to step out onto the log, no less shoot at a target. ”You have much skill with your bow,” the master said, sensing his challenger’s predicament, ”but you have little skill with the mind that lets loose the shot.” The essence of the story is, unless we are master of our mind, our mastery is nothing more that a talent.

Interestingly, concentration is also one of the path to attain self-realization — the ultimate goal of human life. This goal has been stated in several ways such as Nirvana in Buddism, Achieving Unwavering Intelligence in Bhagvad Gita and Attaining the State of Everlasting Bliss (samadhi) in Hindu Philosophy. Nevertheless, concentration is one of the way to attain this goal. It has been mentioned in the Raja-yoga that focusing the mind on the same object for twelve seconds achieves one unit of concentration; twelve such units of concentration (two minutes and twenty-four seconds) make one unit of meditation; twelve such successive units of meditation (twenty-eight minutes and twenty-four seconds) make one unit of lower samadhi; twelve such successive units of lower samadhi (five hours, forty-five minutes and thirty-six seconds) then lead to the meditator to asamprajnata samadhi, the highest samadhi — the finalgoal of spiritual quest.
Lastly, a man of concentration develops unforgettable memory. He can remember whatever he sees and listens forever. Just imagine what miracles can be performed after achieving such a great power. And this power is not hidden anywhere in outside world but within our own mind. A concentrated mind is like a search-light which makes it possible for us to see even the objects lying in distant, dark corner.
The following quotation made by Swami Vivekananda sums up the whole thing. ’Concentration is the essence of all knowledge; the more the power of concentration, the more knowledge is acquired, because this is the one and only method of acquiring knowledge. Even the lowest shoeblack, if he gives more concentration, will black shoes better; the cook with concentration will cook a meal all the better. In making money, or in worshipping God, or in doing anything, the stronger the power of concentration, the better will that thing be done. This is the one call, the one knock, which opens the gates of nature, and lets out floods of light. How has all the knowledge in the world been gained but by the concentration of the powers of the mind? The world is ready to give up its secrets if we only know to knock, how to give it the necessary blow. The strength and force of the blow come through concentration. There is no limit to the power of the human mind. The more concentrated it is, the more power is brought to bear on one point; that is the secret.’
Finally to conclude, We do not know exactly what we are capable of. Its actually a strong commitment to excellence that can manifest the perfection within. In words of Tiya (a metaphorical parrot on a journey to self-discovery):
YOU are much more than what you think YOU are, and You can achieve much more than you are achieving now
