First Pâda: 9. And with reference to immobility

And it is with reference to their immobility that the earth and other inanimate things--the air, the sky, the waters, the mountains--may be spoken of as thinking, 'the earth thinks (dhyâyati) as it were,' and so on. Movelessness hence is characteristic of the intensely meditating person also, and such movelessness is to be realised in the sitting posture only.
