What is the deeper meaning behind the 'tortoise-vision' (Kurma-drishti) analogy that Baba shares in Chapter 19?

The 'tortoise-vision' or Kurma-drishti analogy described in Chapter 19 is a profound illustration of the power of a Guru's grace and a devotee's focused meditation. Baba explains that a mother tortoise on one river bank can nourish her young on the opposite bank with her gaze alone, without providing physical milk or warmth. Similarly, a devotee who constantly meditates on the Guru requires no other form of sustenance. The mother's gaze is the young ones' complete nourishment. This powerful metaphor teaches that the Guru's grace, received through the devotee's unwavering focus and meditation, is all that is necessary for spiritual growth and sustenance on the path.
