"If a person born in a family of dog-eaters takes to the chanting of the holy name of Kṛṣṇa, it is to be understood that in his previous life he must have executed all kinds of austerities and penances and performed all the Vedic yajñas." Another quotation states:
ṛg-vedo ’tha yajur-vedaḥ sāma-vedo ’py atharvaṇaḥ
adhītās tena yenoktaṁ harir ity akṣara-dvayam
"A person who chants the two syllables ha-ri has already studied the four Vedas—Sāma, Ṛg, Yajur and Atharva."
(Sri Caitanya Caritamrta-----1:7:22-----purport).

The Caitanya-bhāgavata confirms that Śrī Caitanya Mahāprabhu, by His birth, has made the whole world peaceful, as in the past Nārāyaṇa protected this earth in His incarnation as Varāha. Because of His protecting and maintaining this world in the present Kali-yuga, Lord Caitanya Mahāprabhu is known as Viśvambhara, which refers to one who feeds the entire world. The movement inaugurated by Śrī Caitanya Mahāprabhu when He was present five hundred years ago is again being propagated all over the world, and factually we are seeing its practical results. People are being saved, protected and maintained by this Hare Kṛṣṇa movement. Thousands of followers, especially Western youths, are taking part in this Hare Kṛṣṇa movement, and how safe and happy they feel can be understood from the expressions of gratitude in their hundreds and thousands of letters. The name Viśvambhara is also mentioned in the Atharva-veda-saṁhitā (3.3.16.5): viśvambhara viśvena mā bharasā pāhi svāhā.
(Sri Caitanya Caritamrta-----1:14:19-----purport).

The Ṛg Veda, Yajur Veda, Sāma Veda, Atharva Veda, Mahābhārata, Pañcarātra and original Rāmāyaṇa are all considered Vedic literature. The Purāṇas that are especially meant for Vaiṣṇavas (such as the Brahma-vaivarta Purāṇa, Nāradīya Purāṇa, Viṣṇu Purāṇa and Bhāgavata Purāṇa) are also Vedic literature. Therefore, whatever is stated in such Purāṇas or in the Mahābhārata and Rāmāyaṇa is self-evident. There is no need for interpretation. The Bhagavad-gītā is also within the Mahābhārata; therefore all the statements of the Bhagavad-gītā are self-evident. There is no need for interpretation, and if we do interpret, the entire authority of the Vedic literature is lost.
(Sri Caitanya Caritamrta-----2:6:137-----purport).

The Brahma-sūtra (1.1.3) confirms this fact also: śāstra-yonitvāt. Commenting upon this Brahma-sūtra aphorism, Śrī Madhvācārya says, "The Ṛg Veda, Yajur Veda, Sāma Veda, Atharva Veda, Mahābhārata, Pañcarātra and the original Vālmīki Rāmāyaṇa are all Vedic literatures. Any literature following the conclusive statements of these Vedic literatures is also to be considered Vedic literature. That literature which does not conform to Vedic literature is simply misleading."
(Sri Caitanya Caritamrta-----2:6:147-----purport).

"There are two kinds of educational systems. One deals with transcendental knowledge (parā vidyā) and the other with material knowledge (aparā vidyā). All the Vedas—the Ṛg Veda, Yajur Veda, Sāma Veda and Atharva Veda, along with their corollaries, known as śikṣā, kalpa, vyākaraṇa, nirukta, chanda and jyotiṣa—belong to the inferior system of material knowledge (aparā vidyā). By parā vidyā one can understand the akṣara—Brahman or the Absolute Truth." As far as the Vedic literature is concerned, the Vedānta-sūtra is accepted as the parā vidyā. Śrīmad-Bhāgavatam is an explanation of that parā vidyā. Those who aspire for liberation (mukti or mokṣa) and introduce themselves as vaidāntika are also equal to those groups aspiring to improve religion (dharma), economic development (artha) and sense gratification (kāma). Dharma, artha, kāma and mokṣa are called catur-varga. They are all within the system of inferior, material knowledge.
(Sri Caitanya Caritamrta-----2:19:17-----purport).

Foolish people try to concoct knowledge by manufacturing something in their brains. That is not the real way of knowledge. Knowledge is śabda-pramāṇa, evidence from the Vedic literature. Śrīla Vyāsadeva is called Mahāmuni. He is also known as Vedavyāsa because he has compiled so many śāstras. He has divided the Vedas into four divisions—Sāma, Ṛg, Yajur and Atharva. He has expanded the Vedas into eighteen Purāṇas and has summarized Vedic knowledge in the Vedānta-sūtra. He also compiled the Mahābhārata, which is accepted as the fifth Veda. The Bhagavad-gītā is contained within the Mahābhārata. Therefore the Bhagavad-gītā is also Vedic literature (smṛti). Some of the Vedic literatures are called śrutis, and some are called smṛtis.
(Sri Caitanya Caritamrta-----2:20:353-----purport).

Vyāsadeva was the son of the great sage Parāśara. Other names for him are Sātyavateya and Kṛṣṇa-dvaipāyana Bādarāyaṇa Muni. As one of the authorities on the Vedas, he divided the original Veda, for convenience, into four divisions—Sāma, Yajur, Ṛg and Atharva. He is the author of eighteen Purāṇas as well as the theosophical thesis Brahma-sūtra and its natural commentary, Śrīmad-Bhāgavatam. He belongs to the Brahma-sampradāya and is a direct disciple of Nārada Muni.
(Sri Caitanya Caritamrta-----3:9:10-----purport).

Studying the Vedānta-sūtra by one's own efforts (the ascending process of knowledge) is a sign of foolishness. On the other hand, he who has attained a taste for chanting this transcendental vibration has actually reached the conclusion of the Vedānta. In this connection, there are two verses in Śrīmad-Bhāgavatam which are very instructive. The purport of the first is that if a person is chanting the transcendental vibration Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, then even if he was born in the family of the lowest of human beings it is to be understood that in his previous lives he performed all types of renunciation, austerities and sacrifice and studied all the Brahma-sūtras. The purport of the second verse is that one who chants the two syllables ha-ri must be considered to have studied all the Vedas—the Ṛg Veda, Atharva Veda, Yajur Veda and Sāma Veda.
(Teachings of Lord Caitanya)

The principal word in the Vedas—praṇava, or oṁkāra—is the sound representation of the Supreme Lord. Therefore oṁkāra should be considered the supreme sound. But Śaṅkarācārya has falsely preached that the phrase tat tvam asi is the supreme vibration. Oṁkāra is the reservoir of all the energies of the Supreme Lord. Śaṅkara is wrong in maintaining that tat tvam asi is the supreme vibration of the Vedas, for tat tvam asi is only a secondary vibration. Tat tvam asi suggests only a partial representation of the Vedas. In several verses of the Bhagavad-gītā (8.13, 9.17, 17.24) the Lord has given importance to oṁkāra. Similarly, oṁkāra is given importance in the Atharva Vedaand the Māṇḍūkya Upaniṣad. In his Bhagavat-sandarbha, Śrīla Jīva Gosvāmīhas given great importance to oṁkāra: "Oṁkāra is the most confidential sound representation of the Supreme Lord." The sound representation or name of the Supreme Lord is as good as the Supreme Lord Himself. By vibrating such sounds as oṁkāra or Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, one can be delivered from the contamination of this material world. Because such vibrations of transcendental sound can deliver a conditioned soul, they are known as tāraka-mantras.
(Teachings of Lord Caitanya)

Thus according to the evidences afforded by various Vedic scriptures, the Supreme Lord Kṛṣṇa is accepted as the ultimate goal of Brahman realization. The Bhagavad-gītā (7.7) confirms that there is nothing superior to Kṛṣṇa. Madhvācārya, one of the greatest ācāryas in Brahmā’s disciplic succession, has stated in his explanation of the Vedānta-sūtra that everything can be seen through the authorities of the scriptures. He has quoted a verse from the Bhaviṣya Purāṇa in which it is stated that the Ṛg Veda, Yajur Veda, Sāma Veda, Atharva Veda, Mahābhārata, Pañcarātra and the original Rāmāyaṇa are actually Vedic evidence. The Purāṇas accepted by the Vaiṣṇavas are also considered Vedic evidence. Indeed, whatever is contained in that literature should be taken without argument as the ultimate conclusion, and all these literatures proclaim Kṛṣṇa to be the Supreme Personality of Godhead.
(Teachings of Lord Caitanya)

The most widely recognized scriptures in the world are the Vedas. The Vedas have been divided into four parts: Sāma, Yajur, Ṛg and Atharva. The subject matter of the Vedas is very difficult for a man of ordinary understanding. For elucidation, the four Vedas are explained in the historical epic called the Mahābhārata and in eighteen Purāṇas. The Rāmāyaṇa is also a historical epic which contains all the necessary information from the Vedas. So the four Vedas, the original Rāmāyaṇa by Vālmīki, the Mahābhārata and the Purāṇas are classified as Vedic literatures. The Upaniṣads are parts of the four Vedas, and the Vedānta-sūtras represent the cream of the Vedas. To summarize all these Vedic literatures, the Bhagavad-gītā is accepted as the essence of all Upaniṣads and the preliminary explanation of the Vedānta-sūtras. One may then conclude that from the Bhagavad-gītā alone one can have the essence of the Vedas, for it is spoken by Lord Śrī Kṛṣṇa, the Supreme Personality of Godhead, who descends upon this material world from the anti-material world in order to give complete information of the superior form of energy.

Dust always accumulates on the streets and roads, so they must be sprinkled with water at least once a day, and in big cities like Calcutta twice a day. The roads of Kuṇḍina were arrayed with colored flags and festoons, and gates were constructed at particular crossings. The whole city was decorated very nicely. The beauty of the city was enhanced by the inhabitants, both men and women, who were dressed in fresh, washed clothes and decorated with sandalwood pulp, pearl necklaces and flower garlands. Incense burned everywhere, and fragrances like aguru scented the air. Priests and brāhmaṇas were sumptuously fed and, according to ritualistic ceremony, were given sufficient wealth and cows in charity. In this way, they were engaged in chanting Vedic hymns. The King's daughter, Rukmiṇī, was exquisitely beautiful. She was very clean and had beautiful teeth. The auspicious sacred thread was tied on her wrist. She was given various types of jewelry to wear and long silken cloth to cover the upper and lower parts of her body. Learned priests gave her protection by chanting mantras from the Sāma Veda, Ṛg Veda and Yajur Veda. Then they chanted mantras from the Atharva Veda and offered oblations in the fire to pacify the influence of different stars.
(Krsna Book).

After satisfying Kṛṣṇa in this way, King Yudhiṣṭhira arranged to perform the Rājasūya sacrifice. He invited all the qualified brāhmaṇas and sages to take part and appointed them to different positions as priests in charge of the sacrificial arena. He invited the most expert brāhmaṇas and sages, whose names are as follows: Kṛṣṇa-dvaipāyana Vyāsadeva, Bharadvāja, Sumantu, Gautama, Asita, Vasiṣṭha, Cyavana, Kaṇva, Maitreya, Kavaṣa, Trita, Viśvāmitra, Vāmadeva, Sumati, Jaimini, Kratu, Paila, Parāśara, Garga, Vaiśampāyana, Atharvā, Kaśyapa, Dhaumya, Paraśurāma, Śukrācārya, Āsuri, Vītihotra, Madhucchandā, Vīrasena and Akṛtavraṇa. Besides all these brāhmaṇas and sages, he invited such respectable old men as Droṇācārya, Bhīṣma (the grandfather of the Kurus), Kṛpācārya and Dhṛtarāṣṭra. He also invited all the sons of Dhṛtarāṣṭra, headed by Duryodhana, and also the great devotee Vidura. Kings from different parts of the world, along with their ministers and secretaries, were also invited to see the great sacrifice performed by King Yudhiṣṭhira, and the citizens, comprising learned brāhmaṇas, chivalrous kṣatriyas, well-to-do vaiśyas and faithful śūdras, all visited the ceremony.
(Krsna Book).

We understand that with the breathing of the Supreme Personality of Godhead there issued forth the four Vedas, namely the Ṛg Veda, the Yajur Veda, the Sāma Veda and the Atharva Veda, and also the histories like the Mahābhārata and all the Purāṇas, which are considered to be the history of the world. The Vedic histories like the Purāṇas and Mahābhārata are called the fifth Veda.
(Krsna Book).

The Vedic literature is divided into two parts: the śrutis and the smṛtis. The śrutis are the four Vedas—Ṛg, Sāma, Atharva and Yajur—and the Upaniṣads, and the smṛtis are the Purāṇas and the Itihāsas like the Mahābhārata, which includes the Bhagavad-gītā. The conclusion of all these is that one should know Śrī Kṛṣṇa as the Supreme Personality of Godhead. He is the Parama-puruṣa, or the Supreme Personality of Godhead, under whose superintendence material nature works. For creation, maintenance and annihilation, the Supreme Lord incarnates into three—Lord Brahmā, Lord Viṣṇu and Lord Śiva—after manifesting the material cosmos. All of these take charge of the three modes of material nature, but the ultimate direction is in the hand of Lord Viṣṇu. The complete activities of material nature under the three modes are conducted under the direction of the Supreme Personality of Godhead, Kṛṣṇa. This is confirmed in the Bhagavad-gītā (mayādhyakṣeṇa (B.G.9:10) and in the Vedas (sa aikṣata).
(Krsna Book).

Therefore the laws of God's nature are neither blind nor accidental, as men with a poor fund of knowledge conclude. Behind the laws of nature is the living brain of God, just as there is always a lawmaker behind all the laws of the state. It does not matter whether or not we see the lawmaker behind the common laws; we must admit that there is a lawmaker. Matter can never work automatically, without a living hand, and therefore we must admit the existence of God, the supreme living being, behind the laws of nature. The Lord says in Bhagavad-gītā that nature works under His superintendence. Nature is only a power, and behind the power is a powerhouse and a brain, just as behind electrical power there is an electrical powerhouse, where everything is conducted by the brain of the resident engineer. The material nature works so nicely, and not blindly, because of the superintendence of the supreme powerful God. In the Vedic hymns (Atharva Veda) the same thing is confirmed. It is only under the superintendence of God that all the natural laws are conducted.
