What are the effects of receiving the Sadguru's grace as detailed in the opening stanzas of Chapter 18?

As detailed in Chapter 18, receiving the Sadguru's grace has a profound and transformative effect. The text explains that if one is fortunate enough to fall within the Guru's grace, the "false logic of 'mine' and 'thine' (this one is ours, that one is a stranger) finds no place." This signifies the elimination of duality and the ego-driven sense of separation, fostering a unitive consciousness. Furthermore, the chapter compares the Guru to rain clouds showering the "water of self-bliss with love," implying that his grace bestows immense joy, peace, and spiritual fulfillment upon the devotee.
