Simply by the advent of Krsna, the entire world became filled with all kinds of auspiciousness. Wherever there is no existence of the Supreme Lord, the path of argument is prominent and the path of disciplic succession is attacked. Sri Krsna, who enjoys variegated spiritual pastimes, is an ocean of nectarean mellows. Wherever a relationship with Krsna is absent, useless mental speculation becomes prominent, which creates quarrel due to the influence of Kali. If the existence of the Supreme Lord is not realized, people who are deceived by the illusory energy of the Lord are made to run after the path of mental speculation and dry argument.
