The six symptoms of fully surrendered souls are also described in this chapter. Devotional service has been divided into two categories — regulative devotional service and spontaneous love. There are sixty-four items listed in regulative devotional service, and out of these sixty-four the last five are considered very important. By practicing even one of the nine processes of devotional service, one can become successful. Speculative knowledge and mystic yoga can never help one in devotional service. Pious activity, nonviolence, sense control and regulation are not separate from devotional service in its pure form. If one engages in devotional service, all good qualities follow. One does not have to cultivate them separately. Spontaneous devotional service arises when one follows a pure devotee who is awakened to spontaneous love of God. Śrī Caitanya Mahāprabhu describes the symptoms of devotees who are already situated in spontaneous love of God. He also describes the devotees who are trying to follow in the footsteps of the pure devotees.
