現前差別故者，第五、現前順受，現謂現在，受正現行，即是受體，現前不違，名現前順受。言差別者，上說五受是差別也。此前所說順樂受等，於此五中是第四異熟順受，由業能招受異熟故，雖業與受體性有殊，而得名為順樂受等。

"As well as by the distinction of present manifestation": fifth, conducive to feeling by present manifestation: "present" means the present time; feeling actively manifesting right now is the essence of feeling itself, and being presently manifested without conflict is called conducive to feeling by present manifestation. The word "distinction" refers to the distinctions among the five feelings discussed above. The previously mentioned conducive to pleasant feeling and so forth are, among these five, the fourth, conducive to feeling by maturation. Because karma is able to bring about the maturation of feeling, although karma and feeling differ in intrinsic nature, they still receive the names "conducive to pleasant feeling" and so forth.
