Arjuna, however, was struck with great wonder after visiting the transcendental world by the grace of Lord Kṛṣṇa. And by the grace of Kṛṣṇa he could understand that whatever opulence there may be within this material world is an emanation from Him. Any opulent position a person may have within this material world is due to Kṛṣṇa’s mercy. One should therefore always be in Kṛṣṇa consciousness, in complete gratefulness to Lord Kṛṣṇa, because whatever one may possess is all bestowed by Him.
Arjuna’s wonderful experience due to the mercy of Kṛṣṇa is one of the many thousands of pastimes performed by Lord Kṛṣṇa during His stay in this material world. They were all unique and have no parallel in the history of the world. All these pastimes prove fully that Kṛṣṇa is the Supreme Personality of Godhead. Yet while present within this material world He played just like an ordinary man with many worldly duties. He played the part of an ideal householder possessing more than 16,000 wives, 16,000 palaces and 160,000 children, and in that role He performed many sacrifices just to teach the royal order how to live in the material world for the welfare of humanity. As the ideal Supreme Personality, He fulfilled the desires of everyone, from the brāhmaṇas, the highest persons in human society, down to the ordinary living entities, including the lowest of men. Just as King Indra is in charge of distributing rain all over the world to satisfy everyone in due course, so Lord Kṛṣṇa satisfies everyone by pouring down His causeless mercy. His mission was to give protection to the devotees and to kill the demoniac kings. Therefore He killed many hundreds and thousands of demons. Some of them He killed personally, and some were killed by Arjuna, who was deputed by Kṛṣṇa. In this way He established many pious kings such as Yudhiṣṭhira at the helm of world affairs. Thus, by His divine arrangement, He created the good government of King Yudhiṣṭhira, and there ensued peace and tranquillity.
