1.176

"The profound mind is the bodhisattva's pure land; when the bodhisattva attains buddhahood, sentient beings endowed with merits come to be born in his land." Sengzhao says: "Planting the mind in the myriad virtues, so deep and firm that it cannot be uprooted, is the profound mind. Furthermore, since one's own mind is deep, those transformed are also deep; and since the cause of the path is deep, the land evoked is naturally complete with merit."
