Observing the festival days outlined in the Vaisnava calendar is an important aspect of devotional practice. Srila Bhaktivedanta Narayana Maharaja always speaks on the appropriate topic on such days, whether it be the appearance or disappearance day of a prominent Vaisnava acarya , the appearance day of an incarnation of Bhagavan, or any other significant day. Of the eleven lectures included within this book, nine are lectures which Srila Maharaja has spoken on significant dates from the Vaisnava calendar. The word prabhanda means an essay and avali means a collection. We are confident that devotees will find this Sri Prabandhavali helpful to their sincere efforts to honour these important days.
