jñasya sājñaṃ jagannāsti vīrasyeva piśācadhīḥ 46

46. pārśva-supta-nara-svapnaḥ iva klībāgrayakṣavat jñasya
sa-ajñam jagat na asti vīrasya iva piśāca-dhīḥ

46. yathā pārśva-supta-nara-svapnaḥ iva klībāgrayakṣavat,
vīrasya iva piśāca-dhīḥ,
tathā jñasya sa-ajñam jagat na asti

46. For the wise person (jña), the world (jagat) steeped in ignorance (sājña) simply does not exist. It is like the dream of a person sleeping nearby (which is unreal to an observer), or like a spirit (yakṣa) appearing only to one who is weak (klība). It is also like the perception of a demon (piśāca-dhī), which holds no reality for a hero (vīra).
