Based on Chapter 45, what are the essential qualities of a 'blessed seeker,' and what role does the Guru play in their journey?

A 'blessed seeker of liberation' possesses several key attributes as described in Chapter 45. Such an individual practices discrimination between the eternal, which is Brahman, and the transient, which is the world. They renounce the fruits of enjoyment in this life and the next and achieve virtues like calmness and self-control. The Guru is absolutely central to this seeker's path. The text advises that the Guru alone is the 'true Brahman,' and the means to liberation is to renounce the transient world and meditate only on the Guru. By developing dispassion and focusing on the Guru as the solid mass of Brahman-consciousness, the seeker achieves the spiritual goal.
