Dhruva Mahārāja actually experienced that upon enlightenment of his senses on the spiritual platform he could understand the essence of Vedic instruction — that the Supreme Godhead is the Supreme Person; He is not impersonal. Dhruva Mahārāja could immediately understand this fact. He was aware that for a very long time he was practically sleeping, and he felt the impetus to glorify the Lord according to the Vedic conclusion. A mundane person cannot offer any prayer or glorify the Supreme Personality of Godhead, because he has no realization of the Vedic conclusion.
When Dhruva Mahārāja, therefore, found this difference within himself, he could immediately understand that it was because of the causeless mercy of the Lord. He offered obeisances to the Lord with great respect and reverence, completely understanding that the Lord's favor was upon him. This spiritual enlivenment of Dhruva Mahārāja's senses and mind was due to the action of the internal potency of the Lord. In this verse, therefore, the word sva-dhāmnā means "by spiritual energy." Spiritual enlightenment is possible by the mercy of the spiritual energy of the Lord. The chanting of the Hare Kṛṣṇa mantra is first addressed to the spiritual energy of the Lord, Hare. This spiritual energy acts when a living entity fully surrenders and accepts his position as an eternal servitor. When a person places himself at the disposal or order of the Supreme Lord, that is called sevonmukha; at that time the spiritual energy gradually reveals the Lord to him.
