So there are four Vedas: Sāma, Yajur, Ṛk, Atharva

So there are four Vedas: Sāma, Yajur, Ṛk, Atharva. Generally they read one Veda, Sāma-vedi, Ṛg-vedi, Yajur-vedi, vedi. But one who studies two Vedas, he is called dvi-vedi, and the apabhraṁśa is du-veda. And one who studies three Vedas, he's called tri-vedi. In... And I mean to say up-country, these titles are still there: vedis, dvi-vedis, tri-vedis, and catur-vedis or co-veda.(?) In Mathurā you'll find the co-vedas. But they have no connection with Vedas now; simply with the name, and begging in the name of dvi, dvi-vedi or tri-vedi, catur-vedi. That... (More...)

As Kṛṣṇa says, vedaiś ca sarvair aham eva vedyaḥ [Bg. 15.15]. By the study of Vedas, if you have attained perfection, then you should know what is Kṛṣṇa. Kṛṣṇa also said. Yatatām api siddhānām [Bg. 7.3]. Siddha means those who are liberated. Liberated means those who have no more the bodily concept of life. They are called liberated, brahma-bhūta [SB 4.30.20]. Prasannātmā. So long one is in the bodily concept of life, he's conditioned. He's conditioned. He's conditioned; he's not liberated. And when one understands fully that he's not this body, he's pure soul, bhāgavata, when he realizes, then that stage is called liberated. So liberated stage is not final. If you simply understand that you are not this body, you are a spirit soul, that is not sufficient. You must act as Brahman. You must act as Brahman. Then you will stay. (More...)

So what Kṛṣṇa will do? How Kṛṣṇa will help? He is coming. He is sending His devotee. He is leaving behind Him the śāstras. Ataeva kṛṣṇa veda-purāṇa karila. The Vedic literature, Veda, Purāṇa... "So I elaborately explained the Vedic ideals in the Purāṇas." Purāṇa means supplementary. They are not to be neglected, the history. Then Mahābhārata, then Vedānta Purāṇa, er, Vedānta philosophy, then explanation of Vedānta philosophy, Śrīmad-Bhāgavatam. And Mahābhārata means which contains Bhagavad-gītā. So many literatures there are. And who has made it? Made it, Vyāsadeva. Vyāsadeva is Kṛṣṇa's incarnation. Vyāsāvatāra. That is stated in the śāstras. So Vyāsadeva made all this literature. That means Kṛṣṇa made through His incarnation. Therefore in the Caitanya-caritāmṛta we find this verse: anādi-bahirmukha jīva kṛṣṇa bhuli' gela, ataeva kṛṣṇa veda purāṇa karila.(?) (More...)

Since you would like to know more about the temple, the worshipers and the scriptures, I beg to inform you that this Krsna consciousness movement is based on the Vedic scriptures. Veda means knowledge, and there are two kinds of knowledge, one mundane and another transcendental. The Vedas are considered to be originally transcendental because they come from the platform which existed before the creation. This transcendental knowledge was impregnated in the heart of the first created living being, and then he distributed the knowledge both for material and spiritual purposes. (More...)

This Vedic knowledge was stated in the Atharva-veda. Later on, just at the beginning of this millennium, the Kali-yuga, Vyasadeva, who is the supreme authority on Vedic knowledge, considering the degraded condition of men in this age, divided the whole Veda into departmental knowledge, and some of his disciples were entrusted with the particular departments. In this way the entire Vedic knowledge was developed into four Vedas, then 108 Upanisads, 18 Puranas, and then summarized in Vedanta-sutra. And then again, to benefit the less intelligent class of men like women, workers, and the degraded descendants of the higher class, Vyasadeva made a fifth Veda, known as Mahabharata, or the great history of India.

The four Vedas-namely the Ṛg-veda, Yajur-veda, Sāma-veda and Atharva-veda-are all emanations from the breathing of the great Personality of Godhead.

Yajñārtha karma, or the necessity of work for the satisfaction of Kṛṣṇa only, is more expressly stated in this verse. If we have to work for the satisfaction of the yajña-puruṣa, Viṣṇu, then we must find out the direction of work in Brahman, or the transcendental Vedas. The Vedas are therefore codes of working directions. Anything performed without the direction of the Vedas is called vikarma, or unauthorized or sinful work. Therefore, one should always take direction from the Vedas to be saved from the reaction of work. As one has to work in ordinary life by the direction of the state, similarly, one has to work under direction of the supreme state of the Lord. Such directions in the Vedas are directly manifested from the breathing of the Supreme Personality of Godhead. It is said: asya mahato bhūtasya naśvasitam etad yad ṛg-vedo yajur-vedaḥ sāma-vedo 'tharvāṅ girasaḥ. "The four Vedas—namely the Ṛg-veda, Yajur-veda, Sāma-veda and Atharva-veda—are all emanations from the breathing of the great Personality of Godhead." The Lord, being omnipotent, can speak by breathing air, as it is confirmed in the Brahma-saṁhitā, for the Lord has the omnipotence to perform through each of His senses the actions of all other senses. In other words, the Lord can speak through His breathing, and He can impregnate by His eyes. In fact, it is said that He glanced over material nature and thus fathered all living entities. After creating or impregnating the conditioned souls into the womb of material nature, He gave His directions in the Vedic wisdom as to how such conditioned souls can return home, back to Godhead. We should always remember that the conditioned souls in material nature are all eager for material enjoyment. But the Vedic directions are so made that one can satisfy one's perverted desires, then return to Godhead, having finished his so-called enjoyment. It is a chance for the conditioned souls to attain liberation; therefore the conditioned souls must try to follow the process of yajña by becoming Kṛṣṇa conscious. Even those who cannot follow the Vedic injunctions may adopt the principles of Kṛṣṇa consciousness, and that will take the place of performance of Vedic yajñas, or karmas.

Vedas are directly manifested from the Supreme Personality of Godhead

Regulated activities are prescribed in the Vedas, and the Vedas are directly manifested from the Supreme Personality of Godhead. Consequently the all-pervading Transcendence is eternally situated in acts of sacrifice. (More...)
