Swamy, it is always good to participate in Prabnadam recitation for pleasing Perumal. He doesn’t bother whether we are reciting from memory or from book. He is simply happy that we are trying. If He is pleased what more do we need?
However, when many experts are reciting from memory, if we sit with the book, our recitation pace may derail their spontaneous flow.. So, it is better not to disturb them. In such situations it is better to be a listener than a reciter.
But, if most members of the Gosthi are like ourselves – seeing the text and slower (compared to the experts), then we can definitely join the Goshti with our text (electronic or printed).
Whether we are a listener or reciter, Perumal is pleased with our attitude and effort.
