Grammatical Analysis
Paṭhavīdhātu: [f.] earth element; element of extension; solidity. Formed by paṭhavī (earth, ground, breadth) + dhātu (element).
Orthodox Definition
Paṭhavīdhātu is the first of the four great physical elements (mahābhūta) constituting all material phenomena (rūpa). In Abhidhamma physics, “earth” does not refer to literal dirt, but to the abstract physical principle of extension, solidity, and resistance.
The commentaries define its characteristic as hardness or softness (kakkhaḷatta-mudduta-lakkhaṇā). Its function is to act as a foundation or receiving platform (patiṭṭhāna-rasā) for the other three elements that arise simultaneously with it.
In meditation practice, identifying the internal earth element involves bringing mindful attention to the solid, resistant parts of the biological body—such as hair, nails, teeth, skin, flesh, sinews, bones, and organs. By observing that this internal solidity is identical in nature to the external dirt of the world, the practitioner abandons the view that the body is “mine.”
