In Mani's teaching his two Roots are placed 'opposite one another on a level.'

And because Mani saw that before him his two elder brethren, namely Marcion and Bardaisan, that one had said, 'below'² and the other 'above'—because he saw that if he said 'below,' that had been said; and if he said 'above,' he saw that it was not new (lit., ancient), not knowing how he should represent the two Entities which he introduced, when he saw that (the arrangement of them) above and below was taken, he represented them as being one opposite the other on a level.
