What is the significance of the 'tortoise-vision' (Kurma-drishti) analogy that Baba uses in his teachings on meditation?

The 'tortoise-vision' or Kurma-drishti analogy, mentioned in Chapter 19, serves as a profound metaphor for the power of focused meditation and divine grace. Baba explains that a mother tortoise on one river bank can nourish her young on the other side with her gaze alone, without providing physical milk or warmth. The young ones simply need to meditate on their mother. This beautifully illustrates how a devotee's focused meditation on the Guru is sufficient nourishment for the soul. As Chapter 19 relays, the mother's gaze is the only sustenance the young need, symbolizing how the Guru's grace, received through constant remembrance and one-pointed meditation, can sustain a devotee on their spiritual journey.
