Bhakti-rasÄyana, or the nectar tonic of bhakti-rasa, consists of the commentaries on a compilation of verses from ÅšrÄ«mad-BhÄgavatam's Tenth Canto that ÅšrÄ«la SanÄtana GosvÄmÄ« included in the final chapter of his ÅšrÄ« Bá¹›had-bhÄgavatÄmá¹›ta. Like stringing peals on a thread, he has composed a necklace of these verses for the benefit of the sÄdhakas (practitioners of bhakti), to stimulate the moods of bhakti in their heart.
