In the śruti-mantra, it is also stated that the absolute whole or Brahman is the ultimate source of everything. Everything emanates from Him, and everything is maintained by Him. And at the end, everything enters into Him. That is the law of nature. In the smṛti-mantra, the same is confirmed. It is said there that the source from which everything emanates at the beginning of Brahmā's millennium and the reservoir to which everything ultimately enters, is the Absolute Truth or Brahman. Material scientists take it for granted that the ultimate source of the planetary system is the sun, but they are unable to explain the source of the sun. Herein, the ultimate source is explained. According to the Vedic literature, Brahmā is the creator of this universe. Yet he had to meditate to get inspiration for such creation. Therefore, neither Brahmā nor the sun is 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.
(Srimad Bhagavatam----1:1:1----purport).

That the Supreme Lord is all-perfect is confirmed in all śruti-mantras. It is said in the śruti-mantras that the all-perfect Lord threw a glance over matter and thus created all living beings. The living beings are parts and parcels of the Lord, and He impregnates the vast material creation with seeds of spiritual sparks, and thus the creative energies are set in motion to enact so many wonderful creations. An atheist may argue that God is no more expert than a watchmaker, but of course God is greater because He can create machines in duplicate male and female forms. The male and female forms of different types of machineries go on producing innumerable similar machines without God's further attention. If a man could manufacture such a set of machines that could produce other machines without his attention, then he could approach the intelligence of God. But that is not possible, for each machine has to be handled individually. Therefore, no one can create as well as God. Another name for God is asamaurdhva, which means that no one is equal to or greater than Him. Paraṁ satyam, or the Supreme Truth, is He who has no equal or superior. This is confirmed in the śruti-mantras.
(Srimad Bhagavatam----1:1:1----purport).

The spiritual exchange or rasa is fully exhibited in spiritual existence between living beings and the Supreme Lord.
The Supreme Personality of Godhead is therefore described in the śruti-mantras, Vedic hymns, as "the fountainhead of all rasas." When one associates with the Supreme Lord and exchanges one's constitutional rasa with the Lord, then the living being is actually happy.
These śruti-mantras indicate that every living being has its constitutional position, which is endowed with a particular type of rasa to be exchanged with the Personality of Godhead. In the liberated condition only, this primary rasa is experienced in full. In the material existence, the rasa is experienced in the perverted form, which is temporary. And thus the rasas of the material world are exhibited in the material form of raudra (anger) and so on.
(Srimad Bhagavatam----1:1:3----purport).

And in the Bhāgavatam they are specifically mentioned in respect to the Supreme Lord. Therefore, while the ladies on the tops of the houses in the capital of the kings of the Kuru dynasty were talking about the Lord, their talk was more pleasing than the Vedic hymns. Anything sung in the praise of the Lord is Śruti-mantra. There are songs of Ṭhākura Narottama dāsa, one of the ācāryas in the Gauḍīya-sampradāya, composed in simple Bengali language. But Ṭhākura Viśvanātha Cakravartī, another very learned ācārya of the same sampradāya, has approved the songs by Ṭhākura Narottama dāsa to be as good as Vedic mantras. And this is so because of the subject matter. The language is immaterial, but the subject matter is important. The ladies, who were all absorbed in the thought and actions of the Lord, developed the consciousness of Vedic wisdom by the grace of the Lord.
(Srimad Bhagavatam----1:10:20----purport).

The material creation is effected by the interaction of the three modes of material nature set in action by the Lord, and therefore it is said here that the Lord existed before the modes of material nature were set in motion. In the Śruti-mantra it is said that only Viṣṇu, the Supreme Lord, existed before the creation, and there was no Brahmā, Śiva or other demigods. Viṣṇu means the Mahā-viṣṇu, who is lying on the Causal Ocean. By His breathing only all the universes are generated in seeds and gradually develop into gigantic forms with innumerable planets within each and every universe. The seeds of universes develop into gigantic forms in the way seeds of a banyan tree develop into numberless banyan trees.
(Srimad Bhagavatam----1:10:21----purport).

The Lord used to live with His 16,108 wives constantly. He expanded Himself into 16,108 plenary portions, and each and every one of them was the Lord Himself without deviation from the Original Personality. The Śruti-mantra affirms that the Lord can expand Himself into many. As husband of so many wives, He pleased them all with presentations, even at a costly endeavor. He brought the pārijāta plant from heaven and implanted it at the palace of Satyabhāmā, one of the principal queens. If, therefore, anyone desires the Lord to become one's husband, the Lord fulfills such desires in full.
(Srimad Bhagavatam----1:10:30----purport).

Here is another manifestation of the feature of His internal potency. He can expand Himself in as many forms of spiritual identity as He desires, even though He is one without a second. It is confirmed by the Śruti-mantra that the Absolute is one alone, and yet He becomes many as soon as He so desires. These manifold expansions of the Supreme Lord are manifested as plenary and separated portions. The separated portions are representations of His energy, and the plenary portions are manifestations of His Personality. Thus the Personality of Godhead manifested Himself in 16,108 plenary expansions and simultaneously entered into each and every one of the palaces of the queens. This is called vaibhava, or the transcendental potency of the Lord. And because He can do so, He is also known as Yogeśvara.
(Srimad Bhagavatam----1:11:31----purport).

Besides that, the śruti confirms that the Supreme Truth Absolute Personality of Godhead never reveals Himself to anyone who is falsely proud of his academic knowledge. The śruti-mantraclearly says (Kaṭha Upaniṣad 1.2.23):
nāyam ātmā pravacanena labhyo
na medhayā na bahunā śrutena
yam evaiṣa vṛṇute tena labhyas
tasyaiṣa ātmā vivṛṇute tanuṁ svām
The whole matter is explained by the Lord Himself, and one who has no approach to the Lord in His personal feature can rarely understand the purport of Śrīmad-Bhāgavatam without being taught by the bhāgavatas in the disciplic succession.
(Srimad Bhagavatam----2:9:36----purport).

He is ajanaḥ, or the Supreme Person, amongst janānām, or all persons. All living entities are individual persons, and amongst all such persons Lord Hari is supreme, as confirmed in the śruti-mantra, nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). So there is no place for impersonal features in the transcendental world as there are impersonal features in the material world. Whenever there is cetana, or knowledge, the personal feature comes in. In the spiritual world everything is full of knowledge, and therefore everything in the transcendental world, the land, the water, the tree, the mountain, the river, the man, the animal, the bird—everything—is of the same quality, namely cetana, and therefore everything there is individual and personal. Śrīmad-Bhāgavatam gives us this information as the supreme Vedic literature, and it was personally instructed by the Supreme Personality of Godhead to Brahmājī so that the leader of the living entities might broadcast the message to all in the universe in order to teach the supreme knowledge of bhakti-yoga.
(Srimad Bhagavatam----2:9:38----purport).

The appearance of an old friend in the form of a brāhmaṇa is very significant. In His Paramātmā feature, Kṛṣṇa is the old friend of everyone. According to Vedic injunction, Kṛṣṇa is sitting with the living entity side by side. According to the śruti-mantra (dvā suparṇā sayujā sakhāyāḥ), the Lord is sitting within the heart of every living entity as suhṛt, the best friend. The Lord is always eager to have the living entity come home, back to Godhead. Sitting with the living entity as witness, the Lord gives him all chances to enjoy himself materially, but whenever there is an opportunity, the Lord gives good counsel and advises the living entity to abandon trying to become happy through material adjustment and instead turn his face toward the Supreme Personality of Godhead and surrender unto Him.
(Srimad Bhagavatam----4:28:51----purport).

The King of the elephants decided to surrender unto Him. This is intelligent. One must know that great Supreme Personality of Godhead and surrender unto Him. The Lord comes personally to instruct us how to be happy, and only fools and rascals do not see by intelligence this supreme authority, the Supreme Person. In the śruti-mantra it is said:
bhīṣāsmād vātaḥ pavate
bhīṣodeti sūryaḥ
bhīṣāsmād agniś candraś ca
mṛtyur dhāvati pañcamaḥ
(Taittirīya Upaniṣad 2.8)
It is out of fear of the Supreme Personality of Godhead that the wind is blowing, that the sun is distributing heat and light, and that death is chasing everyone. Thus there is a supreme controller, as confirmed in Bhagavad-gītā (9.10): mayādhyakṣeṇa prakṛtiḥ sūyate sacarācaram.
(Srimad Bhagavatam----8:2:33----purport).

The place where an earthen pot rests is also earth. Then again, the earthen pot is manufactured by a potter, whose body is a product of earth. The potter's wheel with which the pot is made is an expansion of earth, and the ingredients from which the pot are made are also earth. As confirmed in the śruti-mantra, yato vā imāni bhūtāni jāyante. yena jātāni jīvanti yat prayanty abhisaṁviśanti. The original cause of everything is the Supreme Personality of Godhead, and after being annihilated, everything enters into Him (prakṛtiṁ yānti māmikām). Thus the Supreme Lord, the Personality of Godhead—Lord Rāmacandra or Lord Kṛṣṇa—is the original cause of everything.
(Srimad Bhagavatam----8:3:3----purport).

The living entities are innumerable, but the Lord is one. No one is greater than Him, and no one is equal to Him. Thus the Lord is the supreme worshipable object, as understood from the Vedic mantras (na tat-samaś cābhyadhikaś ca dṛśyate). The Lord is supreme because no one can evaluate Him by mental speculation or jugglery of words. The Lord can travel more quickly than the mind. In the śruti-mantras of Īśopaniṣad it is said:
anejad ekaṁ manaso javīyo
nainad devā āpnuvan pūrvam arṣat
tad dhāvato 'nyān atyeti tiṣṭhat
tasminn apo mātariśvā dadhāti
"Although fixed in His abode, the Personality of Godhead is swifter than the mind and can overcome all others running.
(Srimad Bhagavatam----8:5:26----purport).
