In his Durgama-sangamani commentary on Bhakti-rasamrita-sindhu, Srila Jiva Goswami has explained that the word anusilanam has two meanings. First, it means cultivation through the endeavors to engage and disengage one's body, mind and words. Second, it means cultivation towards the object of our priti, or affection, through manasi-bhava, the sentiments of the heart and mind. Although anusilana is of two types, the cultivation through manasi-bhava is included within cultivation by cesta, one's activities. Hence one's activities or endeavors (cesta) and one's internal sentiments (bhava) are mutually interdependent, and in the end it is the cesta which are concluded to be the sole characteristics of cultivation. Only when the activites of one's body, mind and words are favorably executed for the pleasure of Krishna is it called Bhakti.
