Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura comments that saralatā, or simplicity, is the first qualification of a Vaiṣṇava, whereas duplicity or cunning behavior is a great offense against the principles of devotional service. As one advances in Kṛṣṇa 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.
