Whatever you may want to do in life,
one thing is absolutely indispensable
and at the basis of everything,
the capacity of concentrating the attention.
If you are 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 - what ever it may be,
from the most material physical development
to the highest spiritual one.
There is no spiritual obstacle which can resist
a penetrating power of concentration.
There is nothing in the human or even in the superhuman field,
to which the power of concentration is not the key.
