Jñāneśvarī (commentary on the Bhagavadgītā) 10.176

10.176

svayam evātmanātmānaṃ vettha tvaṃ puruṣottama
bhūtabhāvana bhūteśa devadeva jagatpate
etha āpuleṃ vāḍapaṇa jaiseṃ |
āpaṇaci jāṇije āKāśeṃ |
kāṃ mī yetulī ghanavaṭa aiseṃ |
pṛthvīci jāṇe ||

Just as the sky itself
knows its own vastness,
or the earth alone knows,
'I am this solid,'
