Jñāneśvarī (commentary on the Bhagavadgītā) 6.305

6.305

yuñjann evaṃ sadātmānaṃ yogī niyatamānasaḥ
śāntiṃ nirvāṇaparamāṃ matsaṃsthām adhigacchati
maga brahmaraṃdhrīṃ sthirāonī |
sohaṃbhāvācyā bāhyā pasarūnī |
paramātmaliṃgā dhāṃvonī |
āṃgā ghaḍe ||

Then, having become steady in the brahmarandhra,
and spreading out the arms of the ‘I am He’ consciousness,
it rushes toward the liṅga of the Supreme Self
and embraces it.
