Śrī Rūpa Gosvāmī affirms herein that purification of consciousness, purification of bodily activities, austerities, peace of mind, etc., all become automatically manifest in the person who is engaged in devotional service.
Śrī Rūpa Gosvāmī 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 Him 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-caritāmṛta 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.
There are concrete examples of how a devotee discharged one of these services and achieved perfection. King Parīkṣit achieved the desired goal of life simply by hearing Śrīmad-Bhāgavatam. Śukadeva Gosvāmī achieved the desired goal of life simply by reciting Śrīmad-Bhāgavatam. Prahlāda Mahārāj became successful in his devotional service by always remembering the Lord. Lakṣmī, the goddess of fortune, was successful by engaging herself in massaging the lotus feet of the Lord. King Pṛthu became successful by worshiping in the temple. Akrūra became successful by offering prayers. Hanumān became successful by rendering personal service to Lord Rāmacandra. Arjuna became successful by being a friend of Kṛṣṇa. And Bali Mahārāj became successful simply by offering all of his possessions to Kṛṣṇa.
There are also examples of devotees who discharged all the different items together. In the Ninth Canto, 4th Chapter, 15th, 16th and 17th verses, of the Śrīmad-Bhāgavatam, there is a statement about Mahārāj Ambarīṣa, who followed every one of the devotional processes. In these verses, Śukadeva Gosvāmī says, "King Ambarīṣa first of all concentrated his mind on the lotus feet of Lord Kṛṣṇa and then engaged his speech in describing the pastimes and activities of the Lord. He engaged his hands in washing the temple of the Lord. He engaged his ears in hearing of the transcendental glories of the Lord. He engaged his eyes in seeing the beautiful Deity in the temple. He engaged his body in associating with the pure devotees of the Lord. (When you associate with someone you have to sit down together, eat together, etc.—and in this way the touch of your body with their body is inevitable. Ambarīṣa Mahārāj made his association only with pure devotees and did not allow his body to be touched by anyone else.) He engaged his nostrils in smelling the flowers and tulasī which were offered to Kṛṣṇa, and he engaged his tongue in tasting Kṛṣṇa-prasādam (food prepared specifically for offering to the Lord, the remnants of which are taken by the devotees). Mahārāj Ambarīṣa was able to offer very nice prasādam to Kṛṣṇa because he was a king and had no scarcity of finance. He used to offer Kṛṣṇa the most royal dishes and would then taste the remnants as Kṛṣṇa-prasādam. There was no scarcity in his royal style because he had a very beautiful temple wherein the Deity of the Lord was decorated with costly paraphernalia and offered high grade food. So everything was available, and his engagement was always completely in Kṛṣṇa consciousness."
