Nothing in this world can be thoroughly accomplished without concentration, whether in one's business or profession, or in spiritual work. Those who cannot make a success in their business or profession are the ones whose concentration is not right. And many of those who have succeeded in life owe this to the fact that their concentration is good. They may not know it. There have been many great inventors in the West who have produced wonderful things, yet they themselves did not know that it was due to their concentration that they were able to do so. Some are born with this as a natural gift, and it is because of it that they have made a success of whatever they have undertaken.
