SB 4.9.26
maitreya uvaca
ity arcitah sa bhagavan
atidisyatmanah padam
balasya pasyato dhama
svam agad garuda-dhvajah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The great sage Maitreya said: After being worshiped and honored by the boy [Dhruva Maharaja], and after offering him His abode, Lord Visnu, on the back of Garuda, returned to His abode as Dhruva Maharaja looked on.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
From this verse it appears that Lord Visnu awarded Dhruva Maharaja the same abode in which He resides. His abode is described in the Bhagavad-gita (15.6): yad gatva na nivartante tad dhama paramam mama.
