kakudmi revatim kanyam
svam adaya vibhum gatah
putrya varam pariprastum
brahmalokam apavrtam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Taking his own daughter, Revati, Kakudmi went to Lord Brahma in Brahmaloka, which is transcendental to the three modes of material nature, and inquired about a husband for her.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
It appears that Brahmaloka, the abode of Lord Brahma, is also transcendental, above the three modes of material nature (apavrtam).
