Advaita Vedanta, uniquely among religions, is saying that there is a deeper reality. It calls it Nirguna Brahman without any qualifications or adjectives added to it. The ultimate reality of the universe is not this triangle of God, universe and sentient beings. That's what Krishna is going to talk about in his ninth chapter.
Swami Sarvapriyananda teaches Chapter 9 (Verses 3 - 4) of the Bhagavad Gita. In this series of talks, Swami Sarvapriyananda unfolds the highest truths of Vedanta through the study of the Bhagavad Gita (The Song of God).
