Kṛṣṇa glorifies the knowledge He is about to share. He calls it the ‘rāja-vidyā’, the King of Education, and the ‘rāja-guhyaṁ’, the King of Secrets. It is the highest possible learning because it deals with the source of life itself. It is also ‘pavitram’, the purest knowledge, capable of washing away all material contamination. One of its most beautiful features is that it is ‘su-sukhaṁ kartum’—it is joyfully performed. Unlike difficult penances or dry philosophical logic, the path of devotion (Bhakti) is full of happiness. It involves singing, dancing, and tasting divine food. It is not a struggle of the ego; it is a celebration of the heart. Furthermore, this knowledge gives ‘pratyakṣāvagamaṁ’, or direct perception of the soul. It is not just a theory you have to believe in; it is something you can actually feel and experience in your own life. And because it is ‘avyayam’, the progress you make on this path is eternal. Kṛṣṇa is inviting Arjuna to a spiritual practice that is both effective and profoundly pleasant.
