If you go too far, it'll blow your mind. I mean it's strong out there. If you go out too far beyond the bounds of attention, there are things in the universe, in the universes of mind, in the inner worlds, it's best sometimes not to deal with unless you're very, very far along.
Frederick LenzSit in front of an object of concentration with the eyes open. Focus on a candle flame, or a yantra, a little dot, something small. Just look at it. Focus on it until there is nothing else in your mind. This develops willpower.
