Nyanaponika Thera
Some in the West have considered the Abhidhamma to be the core of what is referred to as "Buddhism and psychology". Other writers on the topic such as Nyanaponika Thera and Dan Lusthaus describe Abhidhamma as a Buddhist phenomenology while Noa Ronkin and Kenneth Inada equate it with Process philosophy. Bhikkhu Bodhi writes that the system of the Abhidhamma Pitaka is "simultaneously a philosophy, a psychology and an ethics, all integrated into the framework of a program for liberation." According to L. S. Cousins, the suttas deal with sequences and processes, while the Abhidhamma describes occasions and events.
