It is a Vedic custom that the junior members of the family should offer respects to the elders every morning. The children or disciples especially should offer their respects to their parents or spiritual master in the morning. In pursuance of this Vedic principle, Lord Kṛṣṇa and Balarāma used to offer Their obeisances to Their parents, Vasudeva and Devakī. One day, after having returned from the sacrificial performances at Kurukṣetra, when Lord Kṛṣṇa and Balarāma went to offer Their respects to Vasudeva, Vasudeva took the opportunity to appreciate the exalted position of his two sons. Vasudeva had the opportunity to understand the position of Kṛṣṇa and Balarāma from the great sages who had assembled in the arena of the sacrifice. Not only did he hear from the sages, but on many occasions he actually experienced that Kṛṣṇa and Balarāma were not ordinary human beings but were very extraordinary. Thus he believed the words of the sages that his sons Kṛṣṇa and Balarāma were the Supreme Personality of Godhead.
With firm faith in his sons, he addressed Them thus: “My dear Kṛṣṇa, You are the sac-cid-ānanda-vigraha (BS 5.1) Supreme Personality of Godhead. And my dear Balarāma, You are Saṅkarṣaṇa, the master of all mystic powers; therefore I have now understood that You are eternal. Both of You are transcendental to this material manifestation and to its cause, the Supreme Person, Mahā-Viṣṇu. You are the original controller of all. You are the resting place of this cosmic manifestation. You are its creator, and You are also its creative ingredients. You are the master of this cosmic manifestation, and actually this manifestation is created for Your pastimes only.
