(Lord Brahma hears the gayatri mantra from Lord Krishna)
May the Lord, who in the beginning of the creation amplified the potent knowledge of Brahmā from within his heart and inspired him with full knowledge of creation and of His own Self, and who appeared to be generated from the mouth of Brahmā, be pleased with me.
As we have already discussed hereinbefore, the Lord, as the Supersoul of all living beings from Brahmā to the insignificant ant, endows all with the required knowledge potent in every living being. A living being is sufficiently potent to possess knowledge from the Lord in the proportion of fifty sixty-fourths, or seventy-eight percent of the full knowledge acquirable. Since the living being is constitutionally part and parcel of the Lord, he is unable to assimilate all the knowledge that the Lord possesses Himself. In the conditioned state, the living being is subject to forget everything after a change of body known as death. This potent knowledge is again inspired by the Lord from within the heart of every living being, and it is known as the awakening of knowledge, for it is comparable to awakening from sleep or unconsciousness. This awakening of knowledge is under the full control of the Lord, and therefore we find in the practical world different grades of knowledge in different persons. This awakening of knowledge is neither an automatic nor a material interaction. The supply source is the Lord Himself (dhiyāṁ patiḥ), for even Brahmā is also subject to this regulation of the supreme creator. In the beginning of the creation, Brahmā is born first without any father and mother because before Brahmā there were no other living beings. Brahmā is born from the lotus which grows from the abdomen of the Garbhodakaśāyī Viṣṇu, and therefore he is known as Aja. This Brahmā, or Aja, is also a living being, part and parcel of the Lord, but being the most pious devotee of the Lord, Brahmā is inspired by the Lord to create, subsequent to the main creation by the Lord, through the agency of material nature. Therefore neither the material nature nor Brahmā is independent of the Lord. The material scientists can merely observe the reactions of the material nature without understanding the direction behind such activities, as a child can see the action of electricity without any knowledge of the powerhouse engineer. This imperfect knowledge of the material scientist is due to a poor fund of knowledge. The Vedic knowledge was therefore first impregnated within Brahmā, and it appears that Brahmā distributed the Vedic knowledge. Brahmā is undoubtedly the speaker of the Vedic knowledge, but actually he was inspired by the Lord to receive such transcendental knowledge, as it directly descends from the Lord. The Vedas are therefore called apauruṣeya, or not imparted by any created being. Before the creation the Lord was there (nārāyaṇaḥ paro 'vyaktāt), and therefore the words spoken by the Lord are vibrations of transcendental sound. There is a gulf of difference between the two qualities of sound, namely prākṛta and aprākṛta. The physicist can deal only with the prākṛta sound, or sound vibrated in the material sky, and therefore we must know that the Vedic sounds recorded in symbolic expressions cannot be understood by anyone within the universe unless and until one is inspired by the vibration of supernatural (aprākṛta) sound, which descends in the chain of disciplic succession from the Lord to Brahmā, from Brahmā to Nārada, from Nārada to Vyāsa and so on. No mundane scholar can translate or reveal the true import of the Vedic mantras (hymns). They cannot be understood unless one is inspired or initiated by the authorized spiritual master. The original spiritual master is the Lord Himself, and the succession comes down through the sources of paramparā, as clearly stated in the Fourth Chapter of the Bhagavad-gītā. So unless one receives the transcendental knowledge from the authorized paramparā, one should be considered useless (viphalā matāḥ), even though one may be greatly qualified in the mundane advancements of arts or science.
Śukadeva Gosvāmī is praying from the Lord by dint of being inspired from within by the Lord so that he could rightly explain the facts and figures of creation as inquired by Mahārāja Parīkṣit. A spiritual master is not a theoretical speculator, like the mundane scholar, but is śrotriyaṁ brahma-niṣṭham (MU 1.2.12).
