वाचां वह्नेर्मुखं क्षेत्रं छन्दसां सप्त धातव: ।

vācāṁ vahner mukhaṁ kṣetraṁ
chandasāṁ sapta dhātavaḥ
jihvā sarva-rasasya ca
brahmā uvāca — Lord Brahmā said; vācām — of the voice; vahneḥ — of fire; mukham — the mouth; kṣetram — the generating center; chandasām — of the Vedic hymns, such as Gāyatrī; sapta — seven; dhātavaḥ — skin and six other layers; havya-kavya — offerings for the demigods and the forefathers; amṛta — food for human beings; annānām — of all sorts of foodstuffs; jihvā — the tongue; sarva — all; rasasya — of all delicacies; ca — also.
Lord Brahmā said: The mouth of the virāṭ-puruṣa [the universal form of the Lord] is the generating center of the voice, and the controlling deity is Fire. His skin and six other layers are the generating centers of the Vedic hymns, and His tongue is the productive center of different foodstuffs and delicacies for offering to the demigods, the forefathers and the general mass of people.
The opulences of the universal form of the Lord are described herein. It is said that His mouth is the generating center of all kinds of voices, and its controlling deity is the fire demigod. And His skin and other six layers of bodily construction are the representative generating centers of the seven kinds of Vedic hymns, like the Gāyatrī. Gāyatrī is the beginning of all Vedic mantras, and it is explained in the first volume of Śrīmad-Bhāgavatam. Since the generating centers are the different parts of the universal form of the Lord, and since the form of the Lord is transcendental to the material creation, it is to be understood that the voice, the tongue, the skin, etc., suggest that the Lord in His transcendental form is not without them. The material voice, or the energy of taking in foodstuff, is generated originally from the Lord; such actions are but perverted reflections of the original reservoirs — the transcendental situation is not without spiritual variegatedness. In the spiritual world, all the perverted forms of material variegatedness are fully represented in their original spiritual identity. The only difference is that material activities are contaminated by the three modes of material nature, whereas the potencies in the spiritual world are all pure because they are engaged in the unalloyed transcendental loving service of the Lord. In the spiritual world, the Lord is the sublime enjoyer of everything, and the living entities there are all engaged in His transcendental loving service without any contamination of the modes of material nature. The activities in the spiritual world are without any of the difficulties of the material world, but there is no question of impersonal voidness on the spiritual platform, as suggested by the impersonalists. Devotional service is defined in the Nārada-pañcarātra as follows:
sevanaṁ bhaktir ucyate
Originally, since all the senses are produced of the Lord’s reservoir of senses, the sensual activities of the material world are to be purified by the process of devotional service, and thus the perfection of life can be attained simply by purifying the present position of our material activities. And the purifying process begins from the stage of being liberated from the conception of different designations. Every living entity is engaged in some sort of service, either for the self, or for the family, or for the society, country, etc., but unfortunately, all such services are rendered due to material attachment. The attachments of the material affinity may be simply changed to the service of the Lord, and thus the treatment of being freed from material attachment begins automatically. The process of liberation is therefore easier through devotional service than by any other methods, for in the Bhagavad-gītā (12.5) it is said that one is subjected to various kinds of tribulations if one is impersonally attached: kleśo ’dhikataras teṣām avyaktāsakta-cetasām.
