Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 29

Sanskrit:

ककुद्मी रेवतीं कन्यां स्वामादाय विभुं गत: ।पुत्र्यावरं परिप्रष्टुं ब्रह्मलोकमपावृतम् ॥ २९ ॥

ITRANS:

kakudmī revatīṁ kanyāṁsvām ādāya vibhuṁ gataḥputryā varaṁ paripraṣṭuṁbrahmalokam apāvṛtam

Translation:

Taking his own daughter, Revatī, Kakudmī went to Lord Brahmā in Brahmaloka, which is transcendental to the three modes of material nature, and inquired about a husband for her.

Purport:

It appears that Brahmaloka, the abode of Lord Brahmā, is also transcendental, above the three modes of material nature (apāvṛtam).
