Jñāneśvarī (commentary on the Bhagavadgītā) 5.19

5.19

jñeyaḥ sa nityasaṃnyāsī yo na dveṣṭi na kāṅkṣati
nirdvaṃdvo hi mahābāho sukhaṃ bandhāt pramucyate
tarī geliyācī se na karī |
na pavatāṃ cāḍa na dharī |
jo suniścaḷu na aṃtarīṃ |
meru jaisā ||

Now, he does not pine for what is gone, / nor does he crave what has not arrived, / and in his heart he is utterly steadfast / like Mount Meru.
