==Why==

The ability of concentration is one of the greatest powers of the human mentality. <ref>http://incarnateword.in/cwsa/21/the-divine-and-the-undivine#p16</ref> Whatever one may want to do in life, one thing is absolutely indispensable and at the basis of everything, the capacity of concentrating the attention. If one is able to gather together the rays of attention and consciousness on one point and can maintain this concentration with a persistent will, nothing can resist it—whatever it may be, from the most material physical development to the highest spiritual one. <ref>http://incarnateword.in/cwm/09/23-july-1958#p15</ref>
