Saṁyutta Nikāya SN 22.22 PTS: S iii 25

At Sāvatthi, the Blessed One addressed the assembled practitioners, saying: “I will teach you the burden, the bearer of the burden, and the putting down of the burden. Listen carefully.

“What is the burden? It should be said that it’s the five sentient processes derived and conditioned by grasping.

These processes: physical form derived and conditioned by grasping, feeling-tones derived and conditioned by grasping, perceptions derived and conditioned by grasping, formative mental events derived and conditioned by grasping, and consciousness derived and conditioned by grasping.

“And who takes up the burden? It should be said that it’s the person who takes up the burden. The person of such-and-such a name and such-and-such a lineage.

“And what is this taking up of the burden? Craving, which makes for further becoming — greed accompanied by delectation and excitement, finding pleasure now here and now there; particularly: craving for sense pleasures, craving for existence, and craving for non-existence. This is called the taking up of the burden.

“And what does it mean to ‘put down the burden’? It is the fading away and cessation of this very craving, without any remainder, forsaking it, renouncing it – complete freedom and non-attachment.

That is what the Blessed One said. Having said this, the well-gone one, the teacher, further said:
“A burden, indeed, these (clung-to) five sentient processes.
The one acquiring this burden is the person.
Taking on this burden is ill-being in the world.
Dropping the burden is well-being.
Casting aside this heavy burden
and not taking up another; removing craving,
with its root (of ignorance) –
one is ‘One Stilled’; one is ‘One Cooled.’
