11.25.21

उपर्युपरि गच्छन्ति सत्त्वेन ब्राह्मणा जना: । तमसाधोऽध आमुख्याद् रजसान्तरचारिण: ॥ २१ ॥

upary upari gacchanti sattvena brāhmaṇā janāḥ tamasādho ’dha ā-mukhyād rajasāntara-cāriṇaḥ

upari upari
higher and higher
gacchanti
they go
sattvena
by the mode of goodness
brāhmaṇāḥ
persons dedicated to Vedic principles
janāḥ
such men
tamasā
by the mode of ignorance
adhaḥ adhaḥ
lower and lower
ā-mukhyāt
headfirst
rajasā
by the mode of passion
antara-cāriṇaḥ
remaining in intermediate situations

Learned persons dedicated to Vedic culture are elevated by the mode of goodness to higher and higher positions. The mode of ignorance, on the other hand, forces one to fall headfirst into lower and lower births. And by the mode of passion one continues transmigrating through human bodies.
