Yogācārabhūmi Śāstra, Fascicle 34 (83)

Original text:如是于修。勤修习者。于时时间应正观察。所有烦恼已断未断。于时时间。于可厌法深心厌离。于时时间。于可欣法深心欣慕。如是名为摄乐作意。彼即于此摄乐作意。亲近修习。多修习故。有能无余永断。修道所断烦恼。最后学位。喻如金刚三摩地生。由此生故。便能永断修道所断一切烦恼。

Explanation: For one who diligently cultivates in this way regarding meditation, at all times one should correctly observe whether all afflictions have already been eradicated or not yet eradicated; at all times, toward the objects that are to be loathed, one should deeply and wholeheartedly become weary of and disenchanted with them; at all times, toward the dharmas that are to be rejoiced in, one should deeply and wholeheartedly feel delight and admiration. This is called the attention of gathering joy (摄乐作意). The practitioner draws near to and cultivates this attention of gathering joy; because of cultivating it repeatedly, one becomes able to eradicate completely and without remainder all the afflictions to be eradicated through the cultivation of the path, and the final stage of learning (aśaikṣa's precursor, the last stage of those still in training) is then born — this stage is likened to the vajra-like meditative absorption (vajra-samādhi). Because this final stage of learning is born, one is then able to forever eradicate all the afflictions to be eradicated through the cultivation of the path.
