The author of Bhakti-rasamrta-sindhu, Srila Rupa Gosvami, very humbly submits that he is just trying to spread Krsna consciousness all over the world, although he humbly thinks himself unfit for this work. That should be the attitude of all preachers of the Krsna consciousness movement, following in the footsteps of Srila Rupa Gosvami. We should never think of ourselves as great preachers, but should always consider that we are simply instrumental to the previous acaryas, and simply by following in their footsteps we may be able to do something for the benefit of suffering humanity.
