Hi Embodied,
As long as we still have ignorance on Tilakkhana and the Four Noble Truths, we will continue to have a sense of self, a self that has aspirations for worldly things and thus will crave for worldly sense pleasures (sankhara paccaya vinnana). And when we crave and acquire sense pleasures, we further accentuate the belief of this self. i.e. we would value highly of this physical body of ours and marvel at our creativity and accomplishments (namarupa paccaya vinnana, vinnana paccaya sankhara). The more we do this back and forth back and forth, the more future existences we are pro-creating for ourselves. The more sankhara we do, the more ignorant we become. The more ignorant we are, the more sankhara we do. It is like a dog going around in circles trying to catch its own tail to no avail.
