।।9.2।।यह सम्पूर्ण विद्याओंका और सम्पूर्ण गोपनीयोंका राजा है? यह अति पवित्र तथा अतिश्रेष्ठ है और इसका फल भी प्रत्यक्ष है। यह धर्ममय है? अविनाशी है और करनेमें बहुत सुगम है अर्थात् इसको प्राप्त करना बहुत सुगम है।
The words raja-vidya mean kingly knowledge, supreme wisdom. As the king is the most supreme ruler this knowledge is the most supreme wisdom. The words raja-guhyam mean the supreme secret or most confidential. True kings are those who possess lofty minds and deep hearts. So this supreme knowledge is appropriate for those also having such minds and hearts. Only people possessing lofty minds and deep hearts possess the discrimination to know what must be kept sacred and confidential from the mundane and profane view. To such persons this knowledge is a sacred mystery and revered. The word pavitram means pure, sanctifying, having the virtue to absolve all impurities which obstruct the attainment of the Supreme Lord Krishna. The word pratyasavagamam means realisation by direct perception. Avagamam is that which is realised and therefore an object of perception. Hence the reality which becomes perceived is in fact consciousness and becomes pratyasavagamam. The purport of this is that by performing bhakti or pure, loving devotional service unto the Supreme Lord, He immediately reveals Himself internally to His surrendered devotee. The word dharmyam meaning eternal righteousness has the virtueof being inseparable from the Supreme Lord. The attribute of dharmyam is known to be the means to achieve spiritual communion with the Supreme Lord. In and of itself the very nature of virtue is happiness. But when the practice of virtue is known to be capable of granting direct access to the Supreme Lord it becomes extremely exhilarating and is so joyful to cultivate as it leads one to the exquisitely blissful goal of attaining the Supreme Lord Krishna. Thus it is susukham kartum or very joyful to perform. This supreme wisdom being so delightful and congenial is what Lord Krishna is about to reveal and must always be embraced with faith in gratitude and love. The word avyayam means imperishable. This means that bhakti or pure, loving devotion does not cease when one attains the Supreme Lord but continues expanding, unabated eternally. What Lord Krishna is declaring is that when His loving devotee achieves this quality of devotion then He immediately delivers Himself to them entirely, feeling that it is insufficient compensation by what He is giving to His bhakta or devotee who has so much love for Him. Lord Krishna feels that even after He has given Himself entirely to His devotee that still this is not enough compensation to reciprocate for their love for Him. This is how inconceivably profoundly Lord Krishna regards His beloved devotees.
