Classical Exegesis
For the discerning (vivekinaḥ), everything (sarvam) is indeed (eva) painful (duḥkham) due to suffering (duḥkhaiḥ) arising from consequences (pariṇāma), from feverishness (tāpa), and from latent impressions (saṁskāra); as well as (ca) the mutual opposition (virodhāt) of the transformations (vṛtti) of the qualities of Nature (guṇa)
