Anyone who traverses the same ground repeatedly will become intimately familiar with its features.
If one has a practice that leans towards freedom, and one explores it thoroughly, then that which one has discovered will become a type of "ground" that can become the foundation of all actions.

Mindful repetition (such as chanting) can be very helpful though when stuck in a groove of ego or self.
The goal is to be free of any concept of self that impairs the free expression of truth and compassion.
