Explain the path to liberation described in the text, including the role of the Guru and 'undifferentiated worship.'

Chapter 45 outlines a specific path for a seeker of liberation. The journey begins with practicing discrimination between the eternal and the transient, renouncing the fruits of enjoyment, and achieving virtues like calmness. A crucial step is to develop self-confidence and renounce hope in worldly support. The central pillar of this path is the Guru. The text states that the Guru alone is the true Brahman, and the means to the goal is to renounce the transient world and meditate solely on the Guru. This constant feeling of devotion leads to dispassion (Vairagya) and ultimately culminates in a state where divinity is perceived in all beings, which is described as 'undifferentiated worship' or Abheda-bhajan.
