Can you explain the concept of internal worship as detailed in Chapter 26?

Chapter 26 describes a form of internal worship that is considered superior to external rituals. This devotional practice involves using pure emotions and faith as offerings. The text poetically suggests 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 in this internal ceremony is the 'eight-petaled lotus of the eight-fold sattvic emotions,' which is to be offered with a focused mind. This method is deemed superior because it is a direct, heartfelt expression of devotion that pleases the Guru and helps the devotee achieve the true fruit of life, transcending physical offerings.
