3.12.9

tāvanna jānāti vidhiḥ khagendra jñāne vidhātuśca svayogyabhūte /
ato viriñcasya na cintanīyo hyajñānaleśaḥ kvāpi deśe ca kāle //

so much Brahmā does not know, O King of Birds, in the knowledge belonging to Brahmā's own capacity. / Therefore, not even the slightest particle of ignorance should be thought of regarding Brahmā in any place or time.
