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

The text posits that being trapped in the eternal cycle of worldly existence, or Samsara, is caused by ignorance. Specifically, it is the deluded knowledge of difference, the belief that "Parabrahman is different from me," which subjects a soul to the endless loop of birth followed by death and then rebirth. Chapter 37 dismisses the desire for a conventional heaven attained through sacrifices and penance, questioning its value. Such a place is seen merely as a realm for sensual enjoyment, and if it lacks the remembrance and chanting of God's name, it is considered useless.
