Talking about opposite worlds or absolute world or complete world is an intellectual style where more explanation, more analysis becomes necessary. Zen only points to the moment world, the world of this moment.
This moment is very important. It has everything in it. In this moment there is infinite time, infinite space. In this moment there is truth, correct life and the Bodhisattva Way. This moment has everything. Also, this moment has nothing. If you attain this moment you attain everything. This is the teaching of Zen Buddhism.
