瑜伽論記 1.83

1.83

有尋等地有三義：有評家第二師云：中間靜慮，尋已離欲者，如欲界入，不淨觀暫折伏，貪非六行離，釋論稍難。至第四卷釋地名中，當廣顯之。第三師釋初師所引文中，唯說上界三無心，不說下地無心眠。問者略解麁相，義彰可知，彼卷末自解五無心，中當具顯。

The stage with investigation and the like has three meanings: The second master among the commentators says: In the intermediate dhyāna, where investigation has already been detached from desire, it is like entering the desire realm and temporarily suppressing greed through the contemplation of impurity, but not detaching through the six aspects of practice; the Commentary is somewhat difficult [here]. When we come to the explanation of the names of the stages in the fourth fascicle, this will be broadly clarified. The third master explains that in the passage cited by the first master, it speaks only of the three mindless [states] of the upper realms, and does not speak of the mindless sleep of the lower stage. The questioner briefly explains the coarse characteristics, and its meaning is clearly knowable; at the end of that fascicle, the five mindless [states] are themselves explained, wherein it will be fully clarified.
