According to the text, what is the nature of death and what are its true causes?

The provided scripture explains death as the process by which something that has come into form from the unmanifest, known as the 'manifest' state, returns to the unmanifest. However, the true spiritual dangers, referred to as the 'nooses of death,' are not this physical transition. As Chapter 37 clarifies, these nooses are Adharma (unrighteousness), ignorance, anger, and hatred. The text further suggests that the cycle of death and rebirth continues for those who perceive themselves as separate from the ultimate reality, Parabrahman.
