It is a Vedic custom that the junior members of the family should offer respects to the elderly persons every morning. The children or the disciples especially should offer their respects to the parents or the spiritual master in the morning. In pursuance of this Vedic principle, Lord Kṛṣṇa and Balarāma used to offer Their obeisances to Their father, Vasudeva, along with his wives. 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 of appreciating 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. He not only heard 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.
