Can you explain the relationship between Renunciation (Nivritti) and Worldly Activity (Pravritti) in the context of a saint's work as described in Chapter 4?

Chapter 4 of the Sai Satcharitra presents a sophisticated view of a saint's methodology. It explains that saints "fill the foundation of Renunciation (Nivritti) and build the temple of Ultimate Truth." This means their core purpose is to establish the path of spiritual detachment and lead people to enlightenment. However, they achieve this goal by working within the world. The text says they build this temple "around the frame of Worldly Activity (Pravritti)," and in doing so, they "easily uplift the devotees." This suggests that, according to Chapter 4, saints do not demand an immediate rejection of the world but rather use worldly life itself as a framework to guide people toward the higher goal of renunciation and ultimate truth.
