What does Chapter 10 mean when it says the Guru 'strikes a nail over the lines of destiny'?

The phrase 'strikes a nail over the lines of destiny,' found in Chapter 10, is a powerful metaphor for the Sadguru's ability to alter a devotee's fate. In many spiritual traditions, destiny is seen as a pre-written script or a set of lines on one's palm. By 'striking a nail' over these lines, the Guru effectively voids or changes what was predetermined. Chapter 10 asserts that by placing faith in the Guru's feet, one can achieve this profound change. It signifies that the Guru's grace and power are supreme, capable of overriding karmic trajectories and granting a new destiny to the devotee, demonstrating that the Guru is the 'one eternal God' with ultimate control.
