How does Chapter 11 advise a devotee to practice worship and show faith in the Guru?

According to Chapter 11, the foundation of worship is to have unwavering faith in the Guru's word, which should be the devotee's metaphorical 'seat.' This practice must be coupled with the renunciation of all worldly desires. The chapter further suggests that the Guru is omnipresent and can be worshipped in various forms, including an idol, fire, the sun, and water. By holding onto the Guru's feet with total devotion, as Chapter 11 describes, the devotee can experience the wonder of the Guru himself fluctuating as the Supreme Brahman, revealing the profound results of such dedicated worship.
