Based on the teachings in Chapter 37, what causes a soul to be trapped in the cycle of worldly existence, and why is the conventional idea of heaven rejected?

Chapter 37 teaches that the primary cause for being trapped in the cycle of birth and death (Samsara) is the ignorance that creates a sense of separation from the divine. A person who believes, "Parabrahman is different from me; I am not that," is always subject to death and rebirth. This cycle turns eternally behind such an individual. The text further explains why the conventional abode of heaven is not desired; it is seen merely as a place for sensual enjoyment. The chapter questions the use of such a place, especially if it lacks the remembrance and chanting of the Lord's name, suggesting that true liberation is found elsewhere.
