1 To speak untruth is a great sin except under a few scripturally well-specified circumstances. See note to text 1.1.22 in this regard. In his Caitanya-śikṣāmṛta, Śrīla Bhaktivinoda Ṭhākura has also enlisted speaking untruth as one of the sins to be avoided by one and all, specifically by devotees of the Supreme Personality of Godhead.
