瑜伽論記 16.119

16.119

解云，凡捨捨有，若在欲界，先無男女眼耳等根。今生上則無所捨，故言容捨下地一切。凡得上地諸根，有者可得，無者不得，如生第三靜慮無喜可得生，第四定無樂可得故，言生上容得一切。

The explanation says: Generally, losing is losing what exists. If in the desire realm, one previously lacked the male, female, eye, ear, and other faculties, now being born above, there is nothing to lose; therefore it says one may lose all of the lower stage. Generally, regarding acquiring faculties of a higher stage, if they exist they can be acquired, and if they do not exist they cannot be acquired; just as being born in the third dhyāna there is no joy to be acquired, and being born in the fourth dhyāna there is no pleasure to be acquired, it says being born above one may acquire all.
