This is the kingl science, the kingly secret, the supreme purifier, realisable by direct intuitional knowledge, according to righteousness, very easy to perform and imperishable.

It is royal knowledge, a royal secret, supremely purifying. It is known by direct experience, in keeping with dharma, very easy to practise, and imperishable.

Krishna praises the teaching with a string of epithets. It is rāja-vidyā, royal knowledge, and rāja-guhya, the royal secret, the sovereign among teachings. It is supremely purifying and known through direct experience, not mere belief. It is in keeping with dharma, very easy to practise, and imperishable. The claim that it is easy is striking after the demanding instructions of earlier chapters. It anticipates the chapter's emphasis on simple devotion, open to anyone, as a direct path to the highest.
