How does Chapter 4 describe the fundamental nature of saints and their selfless mission?

Chapter 4 portrays saints as beings who are naturally liberated and whose presence on Earth is solely for the benefit of others. The text states clearly that their incarnation has no self-interest. Their mission is to counteract irreligion and protect the vulnerable, including the humble, poor, and weak. As mentioned in Chapter 4, saints work to build a foundation of Renunciation (Nivritti) and a 'temple of Ultimate Truth,' skillfully guiding devotees through worldly activities (Pravritti) toward spiritual upliftment. Their purpose is to perform the work of religion and awaken faith, and they conclude their incarnation once this specific task is complete.
