The actual fact is that worshiping the Deity and chanting the glories of the Lord are both within the nine processes of devotional service recommended by Rupa Goswami. Besides chanting and hearing and remembering there are six other recommended activities in devotional service. So if we are able to practice even only one of these activities perfectly, the result will be the same. Or we may execute more than one, we may execute several or even all nine activities in devotional service, but even if we execute one perfectly we shall be completely successful in devotional service.
