The great sage Maitreya continued: Mahārāja Dhruva was very dear to the Supreme Personality of Godhead. When he heard the sweet speeches of the Lord’s chief associates in the Vaikuṇṭha planet, he immediately took his sacred bath, dressed himself with suitable ornaments, and performed his daily spiritual duties. Thereafter he offered his respectful obeisances to the great sages present there and accepted their blessings.
