Those who do not directly worship the Supreme Godhead, Krsna, but who attempt to achieve the same goal by an indirect process, also ultimately achieve the supreme goal, Sri Krsna, as is stated, "After many births the man of wisdom seeks refuge in Me, knowing Vasudeva is all." When a person comes to full knowledge after many births, he surrenders unto Lord Krsna. If one approaches the Godhead by the method mentioned in this verse, he has to control the senses, render service to everyone and engage in the welfare of all beings. It is inferred that one has to approach Lord Krsna, otherwise there is no perfect realization. Often there is much penance involved before one fully surrenders unto Him.
