"Monks, I don't envision even one other fetter fettered
by which beings conjoined go wandering
and transmigrating on for a long, long time like the fetter
of craving. Fettered with the fetter of craving, beings conjoined go
wandering and transmigrating on for a long, long time."
Itivuttaka 15

The eye is endearing & alluring in terms of the world. That is
where this craving, when arising, arises. That is where, when
dwelling, it dwells.
