Chapter 26 says 'without experience, the exhaustion of speech achieves nothing in spirituality.' What does this mean in the context of the chapter?

This statement from Chapter 26 highlights the critical difference between theoretical knowledge and direct spiritual realization. The author acknowledges that simply talking about or hearing about spiritual truths, such as Vedanta, is insufficient. He prays to Sai Baba to make this knowledge meaningful through personal experience, asking, "by Your power, let me experience this knowledge personally." He specifically requests the gift of the 'natural state of union (Sayujya),' which is a state of experiential oneness, not just an intellectual concept. This implies that the ultimate goal of spirituality is a lived reality, not just a well-understood philosophy.
