What is the path for a seeker of liberation, and what is the Sadguru's role in this process?

As outlined in Chapter 45, the path to liberation requires a seeker to practice discrimination between the eternal (Brahman) and the transient (the world). This blessed seeker must renounce the fruits of enjoyment in both this life and the next, and achieve six virtues including calmness and self-control. The Guru's role is central and absolute; the text identifies the Sadguru as the true Brahman and a 'solid mass of Brahman-consciousness.' The primary means to achieve the goal is to renounce the transient world, which gives rise to dispassion (Vairagya), and meditate solely on the Guru. This leads to 'undifferentiated worship' (Abheda-bhajan), where divinity is perceived in all beings.
