Abhijeet: Guruji pranam, 84 khate ki vidya, yeh kaun si vidya hain? mujhe poore visthar me batayen!
Swami Ram Swarup: My blessings to you. Sorry, 84 khate kee vidya ka to mujhe bhi knowledge nahin. Schchai yeh hai ki vishwa mein yadi sachi vidya hai to weh ek Ishwar se hee utpann Charon vedon ka gyan hai aur issey hee vidya bhi kehte hain. Kyunki ismein gyan, karma aur upasana, in teen vidyayon ka vistaar se varnnan hai. I paste my article in this regard-

THREE EDUCATIONS

There are three educations/preach about

(i) knowledge – science etc(Gyan) in Rigved,
At the time of every creation, knowledge of four Vedas emanates direct from God and is originated in the heart of four Rishis in non-sexual creation. In the said process, first of all, the knowledge of Rigved advents and originates in the heart of Rishi Agni. In this Veda though the description of every worldly matter right from straw to God has been mentioned but it speaks especially about matters concerning science of the world. God has described qualities/nature of all materialistic articles of the universe. Therefore, the entire mankind must get the benefit of eternal knowledge of Vedas by knowing about right from straw to Brahma i.e., God. The meaning of “Ric” is that wherein the qualities and nature of all matters have been described and the meaning of Veda is knowledge i.e., true knowledge. These words are used in making the pious word “Rigved”.

(ii) In Yajurved, the form of true, pious deeds have been preached. So, in the absence of listening of Yajurved, we can’t know about real moral duties of students, married persons, vanprasthis and sanyasis. Even the moral and social obligations of King, parents, children etc., can’t be known.

(iii) In Samved there is preach about eternal true worship of God like Yajyen, name jaap, practice of Ashtang yoga by following which an aspirant realises God/attains salvation.

(iv) Shubh karma

(v) contains comprehensive knowledge of medical science.

So, Almighty God who is formless, creates, nurses, destroys and again creates universe. This process is eternal and everlasting. So, at the time of beginning of each non-sexual, the knowledge of above four Vedas emanates direct from God and is originated in the heart of four Rishis. The knowledge is given by the God to the human-beings for their welfare/benefit because until the knowledge is given by somebody, no one can attain the knowledge. In the beginning of the creation, no preacher, guru, acharya, teacher is present there to teach. So, God gives the knowledge.
