If we can stop all thought, then we know that we are beyond thought. We come to this by negation. When every phenomenon has been negatived, whatever remains, that is It. That cannot be expressed, cannot be manifested, because the manifestation will be, again, will.
Patanjali explains this “infilling of nature” by the simile of peasants irrigating fields. Our education and progression simply mean taking away the obstacles, and by its own nature the divinity will manifest itself. This does away with all the struggle for existence.
We can only say ignorance makes the illusion. The question is impossible. Nothing can have worked on the Absolute. There was no cause. Not that we do not know, or that we are ignorant; but It is above knowledge, and cannot be brought down to the plane of knowledge.
There are certain things which we do not know now, but which we can know. It is due to our ignorance that we do not know them. There are certain things which we can never know, because they are much higher than the highest vibrations of knowledge.
Omnipotence and omniscience are obvious qualities and need no argument to prove from the very fact of totality. Brahman is beyond both these and is not a conditioned state; it is the only Unit not composed of many units, the principle which runs through all from a cell to God.
