BG Chap 10 - Vibhūti yoga - the powers of the Lord

In the previous chapters, Kṛṣṇa described bhakti along with intermittent descriptions of His powers. The powers of the Lord knowing which, one understands that the Lord is worthy of worship have been described starting from the seventh chapter. The Lord’s aiśvarya (extraordinary power), a cause of bhakti, is further supported in this chapter with a detailed description of the Lord’s vibhūtis. When a devotee understands Kṛṣṇa’s greatness in detail, he feels increased gratitude for his good fortune of being able to reciprocate intimately with such a great and powerful Lord.

The ṛṣis speak indirectly and the Lord is also fond of indirect statements. The Bhāgavatam says that the Vedic seers and mantras deal in esoteric terms, and that Kṛṣṇa is pleased by such confidential descriptions. The knowledge He is giving now is also somewhat difficult to comprehend. So Kṛṣṇa decides to explain things again. What He is about to speak is even superior to what was spoken before, and Kṛṣṇa speaks this to cause astonishment in Arjuna and give him benefit in the form of producing and increasing his devotion to the Lord. And Kṛṣṇa speaks to Arjuna although he is already knowledgeable because Arjuna is filled with prema and thus would take pleasure in Kṛṣṇa’s words as if drinking nectar. Even a fraction of knowledge about Kṛṣṇa’s otherwise unknowable position inspires us to serve Him.
