"Sri Rupa Gosvami affirms herein that there are nine different kinds of devotional service, which are listed as hearing, chanting, remembering, serving, worshiping the Deity in the temple, praying, carrying out orders, serving Krishna as a friend and sacrificing everything for Him. Each and every one of these processes is so powerful that if anyone follows even one single one of them, he can achieve the desired perfection without fail. For example, if one is attached simply to hearing about the Lord and another is attached to chanting the glories of the name, both will achieve their desired goal in devotional service. In the Caitanya-caritamrita this has been explained. One may execute one, two, three or all the different processes of devotional service, and at the ultimate end he will achieve the desired goal of being established in devotional service."
