When the heart is directed towards one ideal, one object, one point, it develops, but when the heart goes from one point to another it is weakened, for then the fire element of the heart dies. For instance, a little spark can be brought to a blaze if one blows upon it, but the flame is put out by the wind. Why? Because blowing directs the air to one single spark, but the wind goes all around it and extinguishes the flame.
