The way I undestand Satipatthana meditaion means understanding Four Ultimate Realitis.
Four Ultimate Realities (Paramattha Dhammaa) are:
2)The mental factors (Cetasika) i.e Feeling or sensation (Vedana) and Perception (Sanna) which are arise as a result of consciousness (samkhara)
3)Material form (Ruppa) –This includes body, sex and seat of consciousness. The body-decade is composed of the Four Primary Elements –Extension, cohesion, heat, motion (Pathavi, apo, tejo, vayo)
4)Nirvana (Nibbaana) – Nirvana is an unconditioned reality. All other three are conditioned realities.
I appreciate your input.
