There is a strong focus on the "causes and conditions" underlying everything, including human actions. Everything, including the human soul, is impermanent and lacking in reality because it is made up of parts whose current relationship or configuration will not last forever -- very close to "atoms and the void."
Nothing, including human love, is ultimately real or has any significance; and the only real goal is the negative and highly materialistic one of the cessation of all suffering.
From WmJas Tychonievich -- to discover the reasoning behind this, you will need to Read The Whole Thing.

This could explain (as WmJas points out) why Buddhism is the favourite religion of atheists; and why Buddhist philosophy, practices and disciplines have been so amenable to adaptation (and adoption) by the modern Ahrimanic bureaucracies.
My interpretation is that the attempt to keep spirit qualitatively distinct from the material nowadays (if not in the past) 'backfires' (when it is not covertly intended) into consigning the spirit to a realm of therapeutic materialism.
The proper solution is to regard the material as a subtype of of the spiritual - but not qualitatively distinct from the spiritual. As an analogous explanation: the spirit came first and is everything, and the material is a kind of 'concentration' or 'condensation' of the spirit.
Thus, everything material is truly spiritual, and ultimately and potentially has properties of the spiritual; differing only quantitatively.
Which is how resurrection (i.e. eternal life with a body) can be a higher spiritual state than immaterial spirit.
