1.14

pañcadhā vā caturdhā vā bhūr amedhyā viśudhyati | duṣṭā dvidhā tridhā vāpi śodhyate malinaikadhā || dahanaṃ khananaṃ bhūmer upalepanavāpanam | parjanyamārjanaṃ veti śaucaṃ pañcavidhaṃ smṛtam

Having approached Devala, best of sages, / who was seated comfortably on the bank of the Indus, all the sages spoke these words:

Impure ground is purified in five or four ways, defiled ground in two or three, soiled ground in one. Burning, digging, smearing, sowing and washing by rain: these are the five kinds of purification of the ground.
