To clarify, in the previous chapters the symptoms of devotional service were explained along with instructions as to how we may execute devotional service with our present senses and gradually rise to the platform of ecstasy in spontaneous love.

Within the stage of the regulative principles of devotional service there are two divisions—namely executive and effective.
