The Yoga of Royal Knowledge and Royal Secret

Krishna describes this knowledge with eight qualities that reveal its supreme nature. It's raja vidya (royal knowledge)—the highest knowledge, like a king among all knowledge. It's raja guhya (royal secret)—the most confidential secret, like a king's secret. It's pavitram (pure)—free from material contamination, completely pure. It's uttamam (supreme)—the highest, beyond all other knowledge. It's pratyaksha-avagamam (directly realizable)—you can perceive it directly, not through theory alone. It's dharmyam (righteous)—in accordance with dharma, the path of righteousness. It's su-sukham (very easy)—easy to perform, not difficult. It's avyayam (imperishable)—eternal, never perishes. This knowledge is the highest path—pure, direct, easy, and eternal.
