Dear friends in Dhamma,
I have long wondered whether there was any scriptural support for using the wheel as a symbol for Dependent Origination. Ven. Thanissaro also points this out in his 'The Shape Of Suffering', and as far as I have read and recall, there is nothing in the Sutta Pitaka explicitly warranting such symbolism. However, someone once told me that there is a place in the Vinaya where the Buddha allows the Bhikkhus to use the wheel as a symbol for Dependent Origination specifically and the Dhamma generally. I have never been able to locate such a passage, but my Vinaya resources are somewhat shaky.
Can anyone shed light on this mystery quote if such a one exists? Or provide any further scriptural ground for this symbolism?
Metta and peace,
Bowing and thanks,
