I know that there is/are books which explain the reasoning of Buddha, why he established certain rules in the Patimokkha. Does anyone know where to find them?
If I remember right, Bikkhu Bodhi is somehow involved in these.
Hi @Alex70. The reasoning behind the formulation of the PÄtimokkha rules can be found in the Vinaya. (The link is to the Monastic Rules of the TheravÄda school but there are others). Have a look at the vibhaį¹ gas (explanations) for the origin stories of the rules. Monks and Nunās each have their own vibhaį¹ gas.
If youāre super interested, Volume 1 of The Buddhist Monastic Code, translated and explained by į¹¬hÄnissaro Bhikkhu, covers the material in great detail.
Iām not familiar with Bhikkhu Bodhiās work regarding the PÄtimokkha rules but, as far as I know, į¹¬hÄnissaro Bhikkhuās two volumes are the definitive guide for monastics and lay people.
