維摩經略疏 5.124

5.124

問：此經既明入不思議解脫，何得不明入法界耶？答：上轉教觀入不二法門，與華嚴法界不殊，但未證入者至後三味。

Question: Since this sūtra clarifies entering the inconceivable liberation, why does it not clarify entering the dharmadhātu? Answer: Above, transforming teaching and contemplation to enter the nondual Dharma door is not different from the Avataṃsaka's dharmadhātu; however, those who have not realized and entered it proceed to the later three flavors.
