1. Submissiveness, realization, meet Krsna

    His [the Supreme Lord's] existence can be realized by one who has the single qualification of submissiveness and who thereby becomes a surrendered soul. The development of submissiveness is the cause of proportionate spiritual realization, by which one can ultimately meet the Supreme Lord in person, as a man meets another man face to face.
