A. C. Bhaktivedanta Swami Prabhupada - Raja-Vidya - The King of Knowledge

his Knowledge is the king of education, the most secret of all secrets. It is the purest knowledge, and because it gives direct perception of the self by realization, it is the perfection of religion. It is everlasting and it is joyfully performed.From chapter one of the book:As long as we do not surrender, we cannot understand God. Surrender to God may take many births, but if we accept that God is great, it is possible to surrender unto Him immediately. But generally this is not our position in the material world. We are characteristically envious and consequently think, Oh, why should I surrender unto God? I am independent. I shall work independently. Therefore in order to rectify this misgiving, we have to work for many births. In this regard, the name of Krsna is especially significant. Krs means repetition of birth, and na means one who checks. Our repetition of birth can be checked only by God. No one can check his repetition of birth and death without the causeless mercy of God.The subject matter of the Ninth Chapter is raja-vidya. Raja means king, and vidya means knowledge. In ordinary life we find one person king in one subject and another in another subject. This knowledge, however, is sovereign over all others, and all other knowledge is subject or relative to it. The word raja-guhyam indicates that this sovereign knowledge is very confidential, and the word pavitram means that it is very pure. This knowledge is also uttamam; ud means transcend, and tama means darkness, and that knowledge which surpasses this world and the knowledge of this world is called uttamam. It is the knowledge of light, and darkness has been separated from it. If one follows this path of knowledge, he will personally understand how far he has progressed down the path of perfection (pratyaksavagamam dharmyam). Su-sukham kartum indicates that this knowledge is very happy and joyful to execute. And avyayam indicates that this knowledge is permanent. We may work in this material world for education or riches, but these things are not avyayam, for as soon as this body is finished, everything else is also finished. With death, our education, advanced degrees, bank balances, family-everything-are all finished. Whatever were doing in this material world is not eternal. However, this knowledge is not like that.nehabhikrama-naso sti pratyavayo na vidyate svalpam apy asya dharmasya trayate mahato bhayatIn this endeavor there is no loss or diminution, and a little advancement on this path can protect one from the most dangerous type of fear. (Bg. 2.40)Knowledge in Krsna consciousness is so perfect that if one performs work in Krsna consciousness and yet does not attain perfection, in his next life he takes up from wherever he left off. In other words, actions performed in Krsna consciousness are durable. On the other hand, material achievements, because they pertain to the body, are vanquished at death. Knowledge that pertains to designations does not endure. I am thinking that I am a man or a woman, an American or Indian, a Christian or Hinduthese are all designations pertaining to the body, and when the body is finished, they will also be finished. We are actually spirit, and therefore our spiritual activities will go with us wherever we go.Sri Krsna indicates that this king of knowledge is also happily performed. We can easily see that activities in Krsna consciousness are joyfully done. There is chanting and dancing, eating prasadam (food that has been offered to Krsna) and discussing Bhagavad-gita. These are the main processes. There are no stringent rules and regulations that we have to sit so straight for so long or do so many gymnastics, or control our breath. No, the process is very easily and happily done. Everyone wants to dance, to sing, to eat and to hear the truth. This process is truly susukham-very happy
