What is the root cause of suffering and the cycle of birth and death, and how can one overcome it?

According to the teachings in Chapter 37, the root cause of all suffering and the endless cycle of birth and death is ignorance, or 'Avidya'. This ignorance establishes the perception of manifoldness and duality. The text warns that he who holds even the slightest view of difference will fall into the sufferings of birth and death. To overcome this, one must acquire 'Vidya' (knowledge) through the scriptures and the Guru. When this true knowledge is gained, ignorance is removed, the perception of manifoldness vanishes, and the cycle of birth and death ceases for that individual, revealing the profound science of oneness.
