Why does the author of Sai Satcharitra emphasize the need for personal experience over intellectual knowledge in Chapter 26?

Chapter 26 strongly argues for the necessity of personal experience, or 'Anubhava,' in spirituality. The author makes a direct plea to Sai Samarth, stating that 'without experience, the exhaustion of speech achieves nothing in spirituality.' This highlights the belief that mere intellectual understanding or discussion of spiritual concepts is fruitless. The text reveals a deep yearning for the knowledge of the Self to be made meaningful through direct, personal realization. The ultimate goal mentioned is the 'gift of the natural state of union (Sayujya) through Your grace,' which can only be attained through experiential knowledge, not just theoretical learning.
