Based on Chapter 22, what is the ultimate path to happiness for a devotee, and why is the Guru's form so central to this path?

According to Chapter 22, the one and only path for a devotee to achieve absolute fulfillment of happiness is through the Sadguru's feet, stating, "there is no other path for us Except Your feet." The Guru's physical form is central because it provides a tangible focus for meditation and devotion, without which "nothing pleases the mind." The chapter describes how devotees come for a vision, place their heads at Baba's feet, and "plunder personal happiness with love." The story of Das Ganu, also found in Chapter 22, further demonstrates that the Guru's feet are the very source of divine power, containing holy places like Prayag within them, making devotion to the form the complete spiritual practice.
