仁王般若經疏 3.161

3.161

三十忍初地相，第一義諦九地相，是故大王捨凡夫身入六住身，捨七報身入八法身，證一切行般若波羅蜜。

"The thirty patiences are the characteristics of the initial ground; the ultimate truth is the characteristics of the nine grounds. Therefore, Great Kings, abandon the physical body of an ordinary being and enter the body of the six abidings; abandon the seven retributive bodies and enter the eight Dharma bodies, realizing the prajñāpāramitā of all practices."
