但以尋伺推度不推度麁細治別，體非三學無勝利益，故以有言顯其分位，定體是學有勝利益，但言定非地，即顯差殊，不須說有，以同尋伺心體亦無殊勝利益，非學法故，亦以有言辨其差別，說為有心及無心地。

It is simply because investigation and reflection have the distinction of inquiring or not inquiring, coarse or subtle, and their substances are not the three trainings and have no superior benefit; therefore the word "with" is used to reveal their states. The substance of absorption is [part of] the trainings and has superior benefit; merely saying "stages of absorption and non-absorption" reveals the distinction, so there is no need to say "with." Since, like investigation and reflection, the substance of mind also lacks particular superior benefit and is not a dharma of training, the word "with" is also used to differentiate it, speaking of the stages with mind and without mind.
