Comparison: Abhidharma and Kalachakra cosmos

"The Buddhist abhidharma (special topics of knowledge) and Kalachakra (cycles of time)
literatures provide two distinct presentations of cosmology, each for a different purpose. Study
of the abhidharma one is undertaken primarily for developing discriminating awareness
(shes-rab, Skt. prajna) by working with set theory applied to complex system analysis. The
Kalachakra presentation is designed to model the structure of the human body and is primarily
for application in advanced tantric meditation to overcome karma. Each presentation is valid
in the context of its own purpose and neither was formulated for the sake of navigation."
-Alexander Berzin 1987
