Chapter 9: Sloka 2

9.2

rāja-vidyā rāja-guhyaṁ
pavitram idam uttamam
pratyakṣāvagamaṁ dharmyaṁ
su-sukhaṁ kartum avyayam

rāja-vidyā—the king of education; rāja-guhyam—the king of confidential knowledge; pavitram—the purest; idam—this; uttamam—transcendental; pratyakṣa—directly experienced; avagamam—understood; dharmyam—the principle of religion; susukham—very happy; kartum—to execute; avyayam—everlasting.

This 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.
