What does Chapter 39 identify as the root of Ignorance, and what is the ultimate solution for its removal?

The source material from Chapter 39 identifies the root of Ignorance as the sense of difference between God and the devotee, or the belief in duality. This delusion, along with body-consciousness, is what creates the veil that covers our natural state of Knowledge. The solution for its removal is multi-faceted but centers on the Guru's grace. When the 'ointment of the Guru's grace' is applied, the veil of Maya is removed. This process involves the dissolution of the ego, after which Ignorance is destroyed. Ultimately, the text points to devotion as the essential means of release, stating that even Lord Brahma is subject to Maya and finds release only through devotion.
