In this verse the words apavarga-gurur gatih are very significant. According to Srimad-Bhagavatam (1.2.11), the Supreme Lord is the ultimate fact of the Absolute Truth. Brahmeti paramatmeti bhagavan iti sabdyate. The Absolute Truth is realized in three featuresimpersonal Brahman, localized Paramatma and ultimately the Supreme Personality of Godhead, Bhagavan. The word apavarga means liberation. pavarga means material existence. In material existence, one always works very hard but is ultimately baffled. One then dies and has to accept another body to work very hard again. This is the cycle of material existence. Apavarga means just the opposite. Instead of working hard like cats and dogs, one returns home, back to Godhead. Liberation begins with merging into the Brahman effulgence of the Supreme Lord. This conception is held by the jnani-sampradaya, philosophical speculators, but realization of the Supreme Personality of Godhead is higher. When a devotee understands that the Lord is satisfied, liberation, or merging into the effulgence of the Lord, is not very difficult. One has to approach the Supreme Personality of Godhead through the impersonal Brahman effulgence just as one has to approach the sun through the sunshine. It is not very difficult to merge into the impersonal effulgence of the Lord, Brahman, if one has satisfied the Supreme Personality of Godhead.
