How does the philosophy of non-duality relate to the devotional practices mentioned for overcoming fear and realizing God?

Chapter 37 beautifully integrates the philosophy of non-duality with devotional practices. The core philosophical teaching is that fear arises from duality, which is rooted in ignorance (Avidya). To become fearless, one must attain a non-dual intellect by holding onto the Guru's feet. This is complemented by devotional acts that dissolve the ego. The text suggests applying the 'sandalwood paste of pure love,' preparing the 'throne of firm faith,' and bathing God with 'tears of joy.' These acts of devotion, stemming from love, help the devotee serve the non-distinguished state where fear has no place, ultimately leading to the dissolution of the self into the divine.
