dhyāyatīva pṛthivī \
dhyāyatīvāntarikṣam \

1. ‘Meditation (_dhyāna_), assuredly, is more than Thought. The earth meditates, as it were (_iva_). The atmosphere meditates, as it were. The heaven meditates, as it were. Water meditates, as it were. Mountains meditate, as it were. Gods and men meditate, as it were. Therefore whoever among men here attain greatness—they have, as it were, a part of the reward of meditation. Now, those who are small are quarrelers, tale-bearers, slanderers. But those who are superior—they have, as it were, a part of the reward of Meditation. Reverence Meditation.
