Srila Bhaktisiddhanta Sarasvati Thakura comments that saralata, or simplicity, is the first qualification of a Vaisnava, whereas duplicity or cunning behavior is a great offense against the principles of devotional service. As one advances in Krsna consciousness, one must gradually become disgusted with material attachment and thus become more and more attached to the service of the Lord. If one is not factually detached from material activities but still proclaims himself advanced in devotional service, he is cheating. No one will be happy to see such behavior.
