Chapter 26 describes a form of internal worship. Can you explain what this entails and why it's considered superior?

Chapter 26 details a form of internal worship that is deemed superior to external rituals. Instead of physical offerings, the devotee performs a mental or heart-felt puja. As described in Chapter 26, 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,' presented with a focused mind. This internal ritual is considered superior because it is a direct expression of pure love and devotion, which is what truly pleases the Guru and helps the devotee achieve the true fruit of life.
