Saṃyutta Nikāya (SN 35.146):
"What is old kamma? The eye is old kamma, to be seen as generated and fashioned by volition, as something to be felt. The ear… the nose… the tongue… the body… the mind are old kamma, to be seen as generated and fashioned by volition, as something to be felt

37 (7) Not Yours>
At Sāvatthı̄. “Bhikkhus, this body is not yours, nor does it belong to others.110 [65] It is old kamma, to be seen as generated and fashioned by volition, as something to be felt.111 Therein, bhikkhus, the instructed noble disciple attends carefully and closely to dependent origination itself thus: ‘When this exists, that comes to be; with the arising of this, that arises.
Bodhi note 111 Spk: It is old kamma (purāṇam idaṃ kammaṃ): This body is not actually old kamma, but because it is produced by old kamma it is spoken of in terms of its condition. It should be seen as generated (abhisaṅkhata), in that it is made by conditions; as fashioned by volition (abhisañcetayita), in that it is based on volition, rooted in volition; and as something to be felt (vedaniya), in that it is a basis for what is to be felt [Spkpṭ: because it is a basis and object of feeling].

V> . NEW AND OLD 35- 146 (1) bodhi translation
Kamma “Bhikkhus, I will teach you new and old kamma, the cessation of kamma, and the way leading to the cessation of kamma. Listen to that and attend closely, I will speak…. “And what, bhikkhus, is old kamma? The eye is old kamma, to be seen as generated and fashioned by volition, as something to be felt.146 The ear is old kamma … The mind is old kamma, to be seen as generated and fashioned by volition, as something to be felt. This is called old kamma. “And what, bhikkhus is new kamma? Whatever action one does now by body, speech, or mind. This is called new kamma.

We are born in order to receive the results of past kamma. And then we make new kamma in a never ending cycle. Thus the three rounds vipakavatta, kilesa vatta and kamma vatta spin endlessly.
There is the round of defilements (kilesa-vaṭṭa ),
the round of kamma(kamma-vaṭṭa ),
and the round of results(vipāka-vaṭṭa ).
And all without any self, simply processes of nama- rupa.
