"One who engages in full devotional service, who does not fall down in any circumstance, at once transcends the modes of material nature and thus comes to the level of Brahman."
If one is factually engaged in the service of the Lord, bhakti-yoga, he will automatically control his senses, his tongue and so many other things. Once engaged in the bhakti-yoga process with all sincerity, one will have no chance of falling down. Even if one falls down, there is no loss. One's devotional activities may be stunned or choked for the time being, but as soon as there is another chance, the practitioner begins from the point where he left off.
