What is the meaning behind the mother tortoise analogy that Baba used to explain his Guru's method?

Sai Baba used the analogy of the mother tortoise to explain the nature of his Guru's protection and guidance, which was based on a loving gaze rather than physical instruction. As described in Chapter 19, just as a mother tortoise on one riverbank can nurture her young on the other bank with her sight alone, his Guru protected him with a 'merciful glance.' This method transcends physical distance, as Baba felt this protection even when 'on the other side of the ocean.' He used this story to explain to an old woman why he doesn't give mantras, emphasizing that the Guru's loving attention alone is sufficient for the disciple's contentment and spiritual growth.
