What forms of devotional worship are highlighted as important in Chapter 26?

Chapter 26 describes several powerful forms of devotional worship. It posits that the highest forms are internal. The text states that constant company with the Guru is equivalent to studying the Vedas, and listening to His life story is a sacred reading (Parayana). Furthermore, the unceasing chanting of the Guru's name is considered devotional singing and daily meditation. The chapter explicitly calls this internal ritual of worship superior to external offerings, suggesting a devotee should wash the Guru's feet with tears of joy, apply the sandalwood paste of pure love, and offer the 'eight-petaled lotus of the eight-fold sattvic emotions' to please Him and achieve the true goal of life.
