What forms of devotion and worship are described in Chapter 26 as being important to a devotee?

Chapter 26 highlights that internal worship is superior to external rituals. It beautifully describes this internal practice, where a devotee washes the Guru's feet with 'warm tears of joy,' applies the 'sandalwood paste of pure love,' and clothes Him with 'true faith.' As found in Chapter 26, the ultimate offering is the 'eight-petaled lotus of the eight-fold sattvic emotions,' presented with a focused mind to achieve life's true fruit. Furthermore, the chapter redefines daily spiritual practices in the context of devotion to the Guru: his constant company becomes the Vedas, listening to his life story is the sacred reading (Parayana), and the unceasing chanting of his name is the primary meditation.
