Overview
This is the complete, master list of all physical matter (Rūpa) in the Theravāda universe. Everything physical, from the human body to a distant star, is composed entirely of combinations of these 28 irreducible elements. Insight meditators memorize this list to accurately dissect and dismantle the illusion of the physical body.
The List
The 4 Primary Elements (Mahābhūta):
- Earth Element (Solidity).
- Water Element (Cohesion).
- Fire Element (Temperature).
- Wind Element (Motion).
The 24 Derived Elements (Upādā Rūpa): 5-9. The Five Sensitivities (Eye, Ear, Nose, Tongue, Body). 10-13. The Four Sense Objects (Form, Sound, Odor, Taste). 14-15. The Two Sexes (Femininity, Masculinity).
- The Heart-base (Seat of consciousness).
- Physical Life-faculty (Vitality).
- Nutritive Essence.
- Space Element. 20-21. Bodily and Verbal Intimation (Communication). 22-24. Lightness, Pliancy, Wieldiness of matter. 25-28. Production, Continuity, Decay, and Impermanence of matter.
