Describe the key characteristics of a 'blessed seeker of liberation' as outlined in this section of the text.

Chapter 45 details several essential traits of a blessed seeker of liberation. Such a person practices discrimination between the eternal (Brahman) and the transient (the world). They actively renounce the fruits of enjoyment in both this world and the next. This seeker has also achieved the six-fold virtues, such as calmness and self-control. Critically, as Chapter 45 emphasizes, this individual must give up hope in receiving help from others for their spiritual goal. Instead, they must maintain strong self-confidence and gird up their own loins, understanding that, in the end, only one's own self remains to complete the journey to liberation.
