And that is raja-vidya, the Sovereign Knowledge, the kind among sciences because of the abundance of its radiance. Indeed, this knowledge of Brahman shines most brilliantly among all kiinds of learning [The word raja means a king, or figuratively, the greatest; or, derived from the root raj, to shine, it may mean shining.-Tr.] So also, idam, this; is raja-guhyam, the Sovereign Profundity, the kind among profundities; uttamam, the best; pavitram, sanctifier. This knowledge of Brahman, which sanctifies all things that purify, is the greatest. Shine it reduces to ashes in a moment (the results of) all actions-righteous, unrighteous and others-together with their roots, accumulated over many thousands of births, therefore, what to speak of its sanctifying power! Besides, it is pratyaksavagamam, directly realizable, directly perceivable like happiness etc. Even though possessed of many qualities, a thing may be noticed to be contrary to righteousness. The knowledge of the Self is not opposed to righteousness, in that way, but it is dharmyam, righteous, not divorced from righteousness. Eeve so, it may be difficult to practice. Hence the Lord says it is susukham, very easy; kartum to practise, like the knowledge of the distinction among jewels. It is seen (in the world) that, actions which require little effort and are accomplished easily yield meagre results, whereas those that are difficult to accomplish yield great results. Thus the contingency arises that this (knowledge of Brahman), however. which is easily attained, perishes when its result gets exhausted. Therefore the Lord says it is avyayam, imperishable. From the point of view of its result, it is not perishable like (the results of) actions. Hence the knowledge of the Self should be highly regarded.
