9. And on account of the contradiction of the initial statement.
The Pradhâna's being the cause of the world would imply a contradiction of the initial statement, viz. that through the knowledge of one thing all things are to be known. Now, on the principle of the non-difference of cause and effect, this initial statement can only be fulfilled in that way that
through the knowledge of the 'Sat', which is the cause, there is known the entire world, whether sentient or non-sentient, which constitutes the effect. But if the Pradhâna were the cause, the aggregate of sentient beings could not be known through it--for sentient beings are not the effect of a non-sentient principle, and there would thus arise a contradiction.--The next Sûtra supplies a further reason.
