Describe the form of 'internal worship' that the devotee offers to Sai Baba in Chapter 26.

In Chapter 26, the author describes a form of internal worship that is considered superior to external rituals. This profound devotional practice involves using one's own emotions and faith as offerings. The devotee resolves to wash Baba's feet with 'warm tears of joy,' apply the 'sandalwood paste of pure love,' and clothe Him with 'true faith.' Furthermore, the offering consists of the 'eight-petaled lotus of the eight-fold sattvic emotions,' presented with a pure and focused mind. This internal ritual is presented as the way to truly please the Guru and achieve the ultimate fruit of life, highlighting a deep, personal connection over material offerings.
