Śaṅkarācārya's commentary

Fruit: a doing of avidyā; like the glamour cast by a juggler's art; very delusive. Action (karma): Dharma and Adharma. Evil: such as hell (naraka), the animal kingdom. Good: such as the Devas. Mixed: humanity. These three sorts of fruits accrue after death to non-abandoners — to the unenlightened, to the followers of Karma-yoga, to the abandoners (saṃnyāsins) not strictly so called — but never to the real saṃnyāsins, engaged exclusively in the path of knowledge (jñāna-niṣṭha) and belonging to the highest order of saṃnyāsins, the Paramahaṃsa-Parivrājakas. Exclusive devotion to Right Knowledge cannot but destroy avidyā and other seeds of saṃsāra.
