God is described here as paribhūḥ, the greatest of all. No one is greater than or equal to Him. Other living beings are described here as beggars who ask goods from the Lord. The Lord supplies the things the living entities desire. If the entities were equal to the Lord in potency-if they were omnipotent and omniscient—there would be no question of their begging from the Lord, even for so-called liberation. Real liberation means going back to Godhead. Liberation as conceived of by an impersonalist is a myth, and begging for sense gratification has to continue eternally unless the beggar comes to his spiritual senses and realizes his constitutional position.
Only the Supreme Lord is self-sufficient. When Lord Kṛṣṇa appeared on earth five thousand years ago, He displayed His full manifestation as the Personality of Godhead through His various activities. In His childhood He killed many powerful demons, such as Aghāsura, Bakāsura and Śakaṭāsura, and there was no question of His having acquired such power through any extraneous endeavor. He lifted Govardhana Hill without ever practicing weight-lifting. He danced with the gopīs without social restriction and without reproach. Although the gopīs approached Him with a paramour's feelings of love, the relationship between the gopīs and Lord Kṛṣṇa was worshiped even by Lord Caitanya, who was a strict sannyāsī and rigid follower of disciplinary regulations. To confirm that the Lord is always pure and uncontaminated, Śrī Īśopaniṣad describes Him as śuddham (antiseptic) and apāpa-viddham (prophylactic). He is antiseptic in the sense that even an impure thing can become purified just by touching Him. The word "prophylactic" refers to the power of His association. As mentioned in the Bhagavad-gītā (9.30-31), a devotee may appear to be su-durācāra, not well behaved, in the beginning, but he should be accepted as pure because he is on the right path. This is due to the prophylactic nature of the Lord's association. The Lord is also apāpa-viddham because sin cannot touch Him. Even if He acts in a way that appears to be sinful, such actions are all-good, for there is no question of His being affected by sin. Because in all circumstances He is śuddham, most purified, He is often compared to the sun. The sun extracts moisture from many untouchable places on the earth, yet it remains pure. In fact, it purifies obnoxious things by virtue of its sterilizing powers. If the sun, which is a material object, is so powerful, then we can hardly begin to imagine the purifying strength of the all-powerful Lord.
