Those who are already liberated chant and hear the holy name of the Lord, knowing perfectly that to glorify the Lord is the only way to keep oneself in a transcendental position
SB Canto 10.1 to 10.13
The word nivṛtta-tarṣaiḥ refers to one who no longer has any material desires (sarvopādhi-vinirmuktam (CC Madhya 19.170)). One may have many material desires because of contamination in this material world, but when one is completely free from all material desires, he is called nivṛtta-tṛṣṇa, which indicates that he no longer has any thirst for material enjoyment. Svāmin kṛtārtho 'smi varaṁ na yāce (CC Madhya 22.42) (Hari-bhakti-sudhodaya). Materialistic persons want some material profit from executing devotional service, but this is not the purpose of service. The perfection of devotional service lies in complete surrender unto the lotus feet of Kṛṣṇa, with no material desires. One who surrenders in this way is already liberated. Jīvan-muktaḥ sa ucyate. One who is always busy serving Kṛṣṇa, in whatever condition he may live, is understood to be liberated even in this life. Such a person, who is a pure devotee, does not need to change his body; indeed, he does not possess a material body, for his body has already been spiritualized. An iron rod kept constantly within a fire will ultimately become fire, and whatever it touches will burn. Similarly, the pure devotee is in the fire of spiritual existence, and therefore his body is cin-maya; that is, it is spiritual, not material, because the pure devotee has no desire but the transcendental desire to serve the Lord. In text four the word upagīyamānāt is used: nivṛtta-tarṣair upagīyamānāt. Who will chant the glories of the Lord unless he is a devotee? Therefore the word nivṛtta-tarṣaiḥ indicates the devotee, and no one else. These are the remarks of ācāryas like Vīrarāghava Ācārya and Vijayadhvaja. To desire anything other than devotional service will diminish one's freedom from material desires, but when one is free from all such desires one is called nivṛtta-tarṣaiḥ (CC Madhya 19.170).
Vinā paśu-ghnāt. The word paśu means "animal." An animal killer, paśu-ghna, cannot enter into Kṛṣṇa consciousness. In our Kṛṣṇa consciousness movement, therefore, animal killing is completely prohibited.
Uttamaśloka-guṇānuvādāt. The word uttamaśloka means "one who is famous as the best of those who are good." The Lord is good in all circumstances. That is His natural reputation. His goodness is unlimited, and He uses it unlimitedly. A devotee is also sometimes described as uttamaśloka, meaning that he is eager to glorify the Supreme Personality of Godhead or the Lord's devotees. Glorifying the Lord and glorifying the Lord's devotees are the same. Or, rather, glorifying the devotee is more important than glorifying the Lord directly. Narottama dāsa Ṭhākura explains this fact: chāḍiyā vaiṣṇava-sevā, nistāra pāyeche kebā. One cannot be liberated from material contamination without sincerely serving a devotee of Kṛṣṇa.
Bhavauṣadhāt means "from the universal remedy." Chanting the holy name and glorifying the Supreme Lord are the universal remedy for all the miseries of materialistic life. Persons who desire to be freed from this material world are called mumukṣu. Such persons can understand the miseries of materialistic life, and by glorifying the activities of the Lord they can be released from all these miseries. The transcendental sound vibrations concerning the Lord's name, fame, form, qualities and paraphernalia are all nondifferent from the Lord. Therefore the very sound vibration of the Lord's glorification and name are pleasing to the ears, and by understanding the absolute nature of the Lord's name, form and qualities the devotee becomes joyful. Even those who are not devotees, however, enjoy the pleasing narrations of the Lord's transcendental activities. Even ordinary persons not very much advanced in Kṛṣṇa consciousness take pleasure in describing the narrations depicted in Śrīmad-Bhāgavatam. When a materialistic person is purified in this way, he engages in hearing and chanting the glories of the Lord. Because glorification of the Lord's pastimes is very pleasing to the ear and heart of the devotee, it is simultaneously his subject and object.
In this world there are three kinds of men: those who are liberated, those trying to be liberated, and those entangled in sense enjoyment. Of these three, those who are already liberated chant and hear the holy name of the Lord, knowing perfectly that to glorify the Lord is the only way to keep oneself in a transcendental position. Those who are trying to be liberated, the second class, may regard the chanting and hearing of the Lord's holy name as a process of liberation, and they too will feel the transcendental pleasure of this chanting. As for karmīs and persons engaged in sense gratification, they also may take pleasure in hearing the pastimes of the Lord, like His fighting on the Battlefield of Kurukṣetra and His dancing in Vṛndāvana with the gopīs.
The word uttamaśloka-guṇānuvāda refers to the transcendental qualities of the Supreme Lord, such as His affection for mother Yaśodā and His friends the cowherd boys and His loving attitude toward the gopīs. The Lord's devotees like Mahārāja Yudhiṣṭhira are also described by the qualification uttamaśloka-guṇānuvāda. The word anuvāda refers to describing the qualities of the Supreme Lord or His devotees. When these qualities are described, other devotees are interested in hearing them. The more one is interested in hearing about these transcendental qualities, the more one transcendentally enjoys. Everyone, therefore, including the mumukṣus, the vimuktas and the karmīs, should chant and hear the glories of the Lord, and in this way everyone will benefit.
Although the sound vibration of the transcendental qualities of the Lord is equally beneficial to all, for those who are muktas, liberated, it is especially pleasing. As described in Śrīmad-Bhāgavatam, Eighth Canto, Third Chapter, verse twenty, because pure devotees, who no longer have any material desires, surrender fully to the lotus feet of the Lord, they always merge in the ocean of bliss by chanting and hearing the Lord's holy name. According to this verse, devotees like Nārada and other residents of Śvetadvīpa are seen always engaged in chanting the holy name of the Lord because by such chanting they are always externally and internally blissful. The mumukṣus, persons desiring to be liberated, do not depend on the pleasures of the senses; instead, they concentrate fully on becoming liberated by chanting the holy name of the Lord. Karmīs like to create something pleasing to their ears and hearts, and although they sometimes like to chant or hear the glories of the Lord, they do not do it openly. Devotees, however, always spontaneously hear, chant about and remember the activities of the Lord, and by this process they are fully satisfied, even though these may seem like topics of sense gratification. Simply by hearing the transcendental narrations of the Lord's activities, Parīkṣit Mahārāja was liberated. He was therefore śrotramano-'bhirāma; that is, he glorified the process of hearing. This process should be accepted by all living entities.
