The chief engineer of a complicated construction does not personally take part in the construction, but he knows every nook and corner because everything is done under his direction. He knows everything about the construction, both directly and indirectly. Similarly, the Personality of Godhead, who is the supreme engineer of this cosmic creation, knows every nook and corner, although affairs are being carried out by demigods. Beginning from Brahmā down to the insignificant ant, no one is independent in the material creation.
(Srimad Bhagavatam----1:1:1----purport).

According to the Vedic literatures, Brahmā, who may be compared to the sun, is not the ultimate creator. It is stated in this śloka that Brahmā was taught Vedic knowledge by the Personality of Godhead. One may argue that Brahmā, being the original living being, could not be inspired because there was no other being living at that time. Herein it is stated that the Supreme Lord inspired the secondary creator, Brahmā, in order that Brahmā could carry out his creative functions. So, the supreme intelligence behind all creations is the Absolute Godhead, Śrī Kṛṣṇa. In Bhagavad-gītā, Lord Śrī Kṛṣṇa states that it is He only who superintends the creative energy, prakṛti, which constitutes the totality of matter. Therefore, Śrī Vyāsadeva does not worship Brahmā, but the Supreme Lord, who guides Brahmā in his creative activities. In this śloka, the particular words abhijñaḥ and svarāṭ are significant. These two words distinguish the Supreme Lord from all the other living entities. No other living entity is either abhijñaḥ or svarāṭ. That is, no one is either fully cognizant or fully independent. Even Brahmā has to meditate upon the Supreme Lord in order to create.
(Srimad Bhagavatam----1:1:1----purport).

There are 8,400,000 species of living beings beginning from the highest intellectual being, Brahmā, down to the insignificant ant, and all of them are enjoying the material world according to the desires of the subtle mind and gross material body.
(Srimad Bhagavatam----1:2:33----purport).

The first puruṣa is the Kāraṇodakaśāyī Viṣṇu. From His skin holes innumerable universes have sprung up. In each and every universe, the puruṣa enters as the Garbhodakaśāyī Viṣṇu. He is lying within the half of the universe which is full with the water of His body. And from the navel of Garbhodakaśāyī Viṣṇu has sprung the stem of the lotus flower, the birthplace of Brahmā, who is the father of all living beings and the master of all the demigod engineers engaged in the perfect design and working of the universal order.
(Srimad Bhagavatam----1:3:2----purport).

The puruṣa, after creating innumerable universes in the mahat-tattva, entered in each of them as the second puruṣa, Garbhodakaśāyī Viṣṇu. When He saw that within the universe there was only darkness and space, without a resting place, He filled half of the universe with water from His own perspiration and laid Himself down on the same water. This water is called Garbhodaka. Then from His navel the stem of the lotus flower sprouted, and on the flower petals the birth of Brahmā, or the master engineer of the universal plan, took place. Brahmā became the engineer of the universe, and the Lord Himself took charge of the maintenance of the universe as Viṣṇu. Brahmā was generated from rajo-guṇa of prakṛti, or the mode of passion in nature, and Viṣṇu became the Lord of the mode of goodness. Viṣṇu, being transcendental to all the modes, is always aloof from materialistic affection. This has already been explained. From Brahmā there is Rudra (Śiva), who is in charge of the mode of ignorance or darkness. He destroys the whole creation by the will of the Lord. Therefore all three, namely Brahmā, Viṣṇu and Śiva, are incarnations of the Garbhodakaśāyī Viṣṇu. From Brahmā the other demigods like Dakṣa, Marīci, Manu and many others become incarnated to generate living entities within the universe.
(Srimad Bhagavatam----1:3:5----purport).

Within one day's duration of the life of Brahmā (which is calculated by our solar year as 4,300,000 x 1,000 years) there are fourteen Manus. Therefore there are 420 Manus in one month of Brahmā and 5,040 Manus in one year of Brahmā. Brahmā lives for one hundred years of his age, and therefore there are 5,040 x 100 or 504,000 Manus in the duration of Brahmā's life. There are innumerable universes, with one Brahmā in each of them, and all of them are created and annihilated during the breathing time of the puruṣa. Therefore one can simply imagine how many millions of Manus there are during one breath of the puruṣa.
(Srimad Bhagavatam----1:3:5----purport).

The most perfect of living beings is Brahmā, the supreme administrator of one universe. He possesses seventy-eight percent of the attributes in full. All other demigods have the same attributes in less quantity, whereas human beings possess the attributes in very minute quantity. The standard of perfection for a human being is to develop the attributes up to seventy-eight percent in full. The living being can never possess attributes like Śiva, Viṣṇu or Lord Kṛṣṇa. A living being can become godly by developing the seventy-eight-percent transcendental attributes in fullness, but he can never become a God like Śiva, Viṣṇu or Kṛṣṇa. He can become a Brahmā in due course.
(Srimad Bhagavatam----1:3:28----purport).

The duration of a day in the life of Brahmā is 4,320,000,000 solar years. This is stated also in the Bhagavad-gītā. So for this period Brahmājī rests in yoga-nidrā within the body of the Garbhodakaśāyī Viṣṇu, the generator of Brahmā. Thus after the sleeping period of Brahmā, when there is again creation by the will of the Lord through the agency of Brahmā, all the great ṛṣis again appear from different parts of the transcendental body, and Nārada also appears.
(Srimad Bhagavatam----1:6:30----purport).

Brahmā, or the first living being born just after the creation, is the direct son of Nārāyaṇa. Nārāyaṇa, as Garbhodakaśāyī Viṣṇu, first of all entered the material universe. Without spiritual contact, matter cannot create. This principle was followed from the very beginning of the creation. The Supreme Spirit entered the universe, and the first living being, Brahmā, was born on a lotus flower grown out of the transcendental abdomen of Viṣṇu. Viṣṇu is therefore known as Padmanābha. Brahmā is known as ātma-bhū because he was begotten directly from the father without any contact of mother Lakṣmījī. Lakṣmījī was present near Nārāyaṇa, engaged in the service of the Lord, and still, without contact with Lakṣmījī, Nārāyaṇa begot Brahmā. That is the omnipotency of the Lord.
(Srimad Bhagavatam----1:6:34----purport).

One who foolishly considers Nārāyaṇa like other living beings should take a lesson from this. Nārāyaṇa is not an ordinary living being. He is the Personality of Godhead Himself, and He has all the potencies of all the senses in all parts of His transcendental body. An ordinary living being begets a child by sexual intercourse, and he has no other means to beget a child other than the one designed for him. But Nārāyaṇa, being omnipotent, is not bound to any condition of energy. He is complete and independent to do anything and everything by His various potencies, very easily and perfectly. Brahmā is therefore directly the son of the father and was not put into the womb of a mother. Therefore he is known as ātma-bhū. ThisBrahmā is in charge of further creations in the universe, secondarily reflected by the potency of the Omnipotent. Within the halo of the universe there is a transcendental planet known as Śvetadvīpa, which is the abode of the Kṣīrodakaśāyī Viṣṇu, the Paramātmā feature of the Supreme Lord. Whenever there is trouble in the universe that cannot be solved by the administrative demigods, they approach Brahmājī for a solution, and if it is not to be solved even by Brahmājī, then Brahmājī consults and prays to the Kṣīrodakaśāyī Viṣṇu for an incarnation and solution to the problems. Such a problem arose when Kaṁsa and others were ruling over the earth and the earth became too much overburdened by the misdeeds of the asuras. Brahmājī, along with other demigods, prayed at the shore of the Kṣīrodaka Ocean, and they were advised of the descent of Kṛṣṇa as the son of Vasudeva and Devakī. So some people say that the Lord appeared because of the prayers of Brahmājī.
(Srimad Bhagavatam----1:6:34----purport).

There are two types of dissolution of the manifested cosmos. At the end of every 4,320,000,000 solar years, when Brahmā, the lord of one particular universe, goes to sleep, there is one annihilation. And at the end of Lord Brahmā's life, which takes place at the end of Brahmā's one hundred years of age, in our calculation at the end of 8,640,000,000 x 30 x 12 x 100 solar years, there is complete annihilation of the entire universe, and in both the periods both the material energy called the mahat-tattva and the marginal energy called jīva-tattva merge in the person of the Supreme Lord. The living beings remain asleep within the body of the Lord until there is another creation of the material world, and that is the way of the creation, maintenance and annihilation of the material manifestation.
(Srimad Bhagavatam----1:10:21----purport).

When Brahmājī and other demigods want to consult Lord Viṣṇu, the plenary portion of Lord Kṛṣṇa, they have to wait on the shore of the ocean of milk where Lord Viṣṇu is lying on White Land (Śvetadvīpa). This ocean of milk and the Śvetadvīpa planet are the replica of Vaikuṇṭhaloka within the universe. Neither Brahmājī nor the demigods like Indra can enter into this island of Śvetadvīpa, but they can stand on the shore of the ocean of milk and transmit their message to Lord Viṣṇu, known as Kṣīrodakaśāyī Viṣṇu.
(Srimad Bhagavatam----1:11:8----purport).

There are fourteen Manus in one day of Brahmā, and the Manu referred to herein is the seventh Manu, who is one of the prajāpatis (those who create progeny), and he is the son of the sun-god. He is known as the Vaivasvata Manu. He had ten sons, and Mahārāja Ikṣvāku is one of them. Mahārāja Ikṣvāku also learned bhakti-yoga as taught in the Bhagavad-gītā from his father, Manu, who got it from his father, the sun-god. Later on the teaching of the Bhagavad-gītā came down by disciplic succession from Mahārāja Ikṣvāku, but in course of time the chain was broken by unscrupulous persons, and therefore it again had to be taught to Arjuna on the Battlefield of Kurukṣetra. So all the Vedic literatures are current from the very beginning of creation of the material world, and thus the Vedic literatures are known as apauruṣeya (not made by man). The Vedic knowledge was spoken by the Lord and first heard by Brahmā, the first created living being within the universe.
(Srimad Bhagavatam----1:12:19----purport).

Lord Śiva and Lord Brahmā are two chiefs of the demigods. They are full of mystic powers. For example, Lord Śiva drank an ocean of poison of which one drop was sufficient to kill an ordinary living being. Similarly, Brahmā could create many powerful demigods, including Lord Śiva. So they are īśvaras, or lords of the universe. But they are not the supreme powerful. The supreme powerful is Govinda, Lord Kṛṣṇa. He is the Transcendence, and His transcendental attributes cannot be measured even by such powerful īśvaras as Śiva and Brahmā. Therefore Lord Kṛṣṇa is the exclusive shelter of the greatest of all living beings. Brahmā is counted amongst the living beings, but he is the greatest of all of us.
(Srimad Bhagavatam----1:18:14----purport).

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.
(Srimad Bhagavatam----2:4:22----purport).

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.
(Srimad Bhagavatam----2:4:22----purport).

As soon as Brahmā was born of the abdominal lotus petals of Viṣṇu, he was impregnated with Vedic knowledge, and therefore he is known as veda-garbha, or a Vedāntist from the embryo. Without Vedic knowledge, or perfect, infallible knowledge, no one can create anything. All scientific knowledge and perfect knowledge are Vedic. One can get all types of information from the Vedas, and as such, Brahmā was impregnated with all-perfect knowledge so that it was possible for him to create. Thus Brahmā knew the perfect description of creation, as it was exactly apprised to him by the Supreme Lord Hari. Brahmā, on being questioned by Nārada, told Nārada exactly what he had heard directly from the Lord.
