What is the path to attaining the Guru's knowledge, and what are the benefits of their grace?

According to Chapter 18, the knowledge of the Guru is attained through a combination of loving worship of God, service to the Guru, and worship of the Guru, with other methods being considered hollow. The Guru's word is described as a "ray of light" and a "smooth guide" on the difficult path of life, which is often obscured by distraction and ignorance. The text beautifully illustrates the benefits of the Guru's grace, stating that by their compassion, worldly desires vanish. Through their grace, wisdom and renunciation, described as "twin fruits," come into one's hands, and one may even speak of knowledge in their sleep.
