Itivuttaka 14
This was said by the Blessed One, said by the Arahant, so I have heard: “Monks, I don’t envision even one other hindrance–hindered by which people go wandering & transmigrating on for a long, long time–like the hindrance of ignorance. Hindered by the hindrance of ignorance, people go wandering & transmigrating on for a long, long time.”
No one other thing
so hinders people
that they wander on, day & night,
as when they’re obstructed
by delusion.
But those who, letting go of delusion,
shatter the mass of darkness,
wander no further.
Their cause isn’t found.
