How is the Guru identified with Brahman, and what does this mean for the disciple's path?

Chapter 45 establishes a profound identity between the Guru and the ultimate reality, stating, "Brahman is eternal, the world is transient; the Guru alone is the true Brahman." The Sadguru is described as a "solid mass of Brahman-consciousness." For the disciple's path, this means the Guru is the living embodiment of the eternal, providing a direct focus for meditation and worship. The disciple's practice is to renounce the transient world, which gives rise to dispassion (Vairagya), and to meditate solely on the Guru. This constant feeling and focus on the Guru as Brahman is presented as the primary means for the disciple to achieve their spiritual goal and realize divinity in all beings through "undifferentiated worship."
