What are the two paths of life described in the Shri Sai Satcharitra, and which one is recommended?

In Chapter 17 of the Shri Sai Satcharitra, two distinct paths are described: Shreya and Preya. Shreya is presented as the path of the Good, associated with discrimination, wisdom (Vidya), and ultimate salvation. In contrast, Preya is the path of the Pleasant, characterized by worldly joy, ignorance (Avidya), and attachment to sensory objects. The text strongly recommends choosing the path of Shreya, stating that to discard Preya and honor Shreya is the true purpose of human life. It uses the metaphor of a wise swan that drinks only pure milk from a mixture of milk and water, illustrating how the wise should cling only to Shreya and turn away from worldly temptations.
