MN 1:27.1–27.4

Yopi so, bhikkhave, bhikkhu sekkho appattamānaso anuttaraṁ yogakkhemaṁ patthayamāno viharati, sopi pathaviṁ pathavito abhijānāti; pathaviṁ pathavito abhiññāya pathaviṁ mā maññi, pathaviyā mā maññi, pathavito mā maññi, pathaviṁ meti mā maññi, pathaviṁ mābhinandi. Taṁ kissa hetu? ‘Pariññeyyaṁ tassā’ti vadāmi.

A mendicant who is a trainee, who hasn’t achieved their heart’s desire, but lives aspiring to the supreme sanctuary from the yoke, directly knows earth as earth. Having directly known earth as earth, let them not conceive it to be earth, let them not conceive it in earth, let them not conceive it as earth, let them not conceive that ‘earth is mine’, let them not approve earth. Why is that? So that they may completely understand it, I say.
