Along a similar theme to Chris' question about instantaneous rebirth, I would like to ask if there are any references to the "wheel of life" in the suttas?
I know there is the concept of the Wheel of Dhamma (dhammacakka), but I'm wondering whether the notion of a "wheel of life" (let alone the conventional 12-spoked version, based on the twelve nidanas of dependent origination) had any grounding in the suttas?
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
