俱舍論頌疏論本 4.73

4.73

釋曰：上兩句明自性，下兩句明所依。得謂獲成就者，釋得自性。得有二種：一獲、二成就也。獲中有二：一未得今獲、二已失今獲。故論云：「未得已失今獲。」解云：未得今獲者，如未得戒，今受得戒，創至生相，將成就故，名為今獲。已失今獲者，如先坐定，遇緣便捨定，名為已失。後重修得，創至生相，將成就故，名為今獲。言成就者，先未得法今時已得，先已得者今復不失。此所得法流至現在，名為成就。故論云：「得已不失，名為成就。」故知獲時不名成就，成就時不名獲也。

The commentary explains: The upper two lines explain intrinsic nature, and the lower two lines explain the support. "Acquisition is gaining and possession" explains the intrinsic nature of acquisition. Acquisition is of two kinds: (1) gaining (lābha) and (2) possession (samanvāgama). Within gaining there are two kinds: (a) gaining now what was not yet acquired, and (b) gaining now what had already been lost. Therefore the Śāstra says: "gaining now what was not yet acquired or what was already lost." The explanation states: "gaining now what was not yet acquired" refers, for example, to one who had not yet acquired the precepts and now receives and acquires the precepts; newly arriving at the characteristic of arising, being on the verge of possession, it is called "gaining now." "Gaining now what was already lost" refers, for example, to one who previously sat in absorption and, meeting with conditions, relinquished the absorption, which is called "already lost"; later, cultivating and acquiring it again, newly arriving at the characteristic of arising, being on the verge of possession, it is called "gaining now." As for "possession": a factor not previously acquired is now acquired, or what was already acquired previously is now not lost again; this acquired factor flowing into the present is called "possession." Therefore the Śāstra says: "Having acquired it, not losing it is called possession." Thus we know that at the time of gaining it is not called possession, and at the time of possession it is not called gaining.
