Śaṅkarācārya's commentary

From man down to unmoving objects below, and from him up to the abode of Brahmā the Creator, whatever regions are attained as the suitable reward of knowledge and action — each varying according to the character of knowledge or of action — they are the spreading branches as it were of that Tree; they are nourished and fattened by the guṇas of Sattva, Rajas and Tamas, which form their material basis (upādāna). The sense-objects such as sound are the buds sprouting from the branches of the physical and other bodies which are the result of actions. The Highest Root of the Tree of Saṃsāra has been mentioned already; now are mentioned the secondary roots — viz., the latent impressions (vāsanās) of the feelings of attachment and aversion, which were caused by the fruits of actions. These roots are spread in this world of man below — below the regions of Devas and the like — and give rise to acts of dharma and adharma. Those roots are spread especially in the world of man; it is while here that men concern themselves with action.
