Can you describe the practices of internal worship and devotion that are mentioned in Chapter 26?

Chapter 26 details a form of internal, mental worship that is considered superior to external rituals. The devotee envisions a deeply personal and symbolic form of service to the Guru. As the chapter explains, this involves washing the Guru's feet with 'warm tears of joy,' applying the 'sandalwood paste of pure love,' and clothing Him with 'true faith.' The ultimate offering is the 'eight-petaled lotus of the eight-fold sattvic emotions,' which is offered with a focused mind to achieve life's true purpose. This internal ritual, as portrayed in Chapter 26, is a method to please the Guru and is complemented by other devotional practices like treating the Guru's company as scripture and the constant chanting of His name as a form of meditation.
