Yoga is so bitter that it blinds us. We are constantly tempted to see and 
hear what we want to see and hear. 
     (19) It is therefore incumbent upon us, if we wish to make the 
universal and final Yoga with the Absolute, to master every element of 
our being, to protect it against all civil and external war, to intensify every 
faculty to the utmost, to train ourselves in knowledge and power to the 
utmost; so that at the proper moment we may be in perfect condition to 
fling ourselves up into the furnace of ecstasy which flames from the abyss 
of annihilation. 
     Love is the law, love under will.
