Personally, it is joy. It is abundance. It is not just the highest purpose it is purposefulness itself.
Systemically, grace is gifting, continual gifting and gifting back. It is freedom and free flowingness. Because it is process itself grace is the actual most basic woof and warp of the cosmos.
Pursuit of paradigm perception and paradigm change is the greatest pursuit of grace.
Grace/graciousness is love inwardly and also love in action, and no matter whether you attribute it to yourself or someone outside yourself, it exists, it is an actual and continual existential reality and even though there be other realities and occurences in the temporal universe these are apparencies-maya and not the deep and more basic truth.
