維摩經玄疏 2.35

2.35

As for what is called the "contemplation of entering emptiness from the provisional": nonexistent yet posited unreal, this is termed "provisional." Contemplating the provisional and knowing nonexistence, like an illusion or transformation, existing merely as a name, one immediately enters emptiness. As for why it is spoken of as the "contemplation of the two truths," it is either the two truths of sentiment and wisdom, or in terms of the two truths according with wisdom.
