But he who is endowed with qualities, and performs works that are to bear fruit, and enjoys the reward of whatever he has done, migrates through his own works, the lord of life, assuming all forms, led by the three Gunas, and following the three paths.

In plain words: The individual soul takes on qualities and does actions that bring results. It enjoys or suffers what it has done, and so it moves from life to life in many forms. It is driven by the three Gunas (the basic qualities of nature: calm, restless and dull) and travels the three paths of different rebirths.
