The preface to the Shri Sai Satcharita mentions the 'sacrifice of knowledge' or 'Jnana-yagna.' How does the text explain this concept and its ultimate reward?

The preface in Chapter 0 explains that by consuming the 'spiritual treat' of the Shri Sai Satcharita with faith and encouraging others to do so, devotees perform a 'sacrifice of knowledge,' or Jnana-yagna. This act satisfies Shri Sai-Paramatma. The text further elaborates with verses from the Dnyaneshwari, which state that one who reads faithfully offers the ignorance of the ego as an oblation into the fire of knowledge, thereby satisfying the Supreme Soul. The ultimate reward for this spiritual practice, as mentioned in Chapter 0, is that after the death of the body, the seeker will undoubtedly become one with the six-fold glorious Shri Sai-Paramatma.
