English Art/Literary Social Science, Sociology, Ethics, etc. consilience between views by Lynne Twist and Christina Figueres - Tom Rivet-Carnac

Dear colleagues,
I find it a bit difficult to understand what the author means by “Life echoes in these reverberant, consilient ways” towards the end of the passage below, which is about the view by Christina Figueres and Tom Rivet-Carnac.
Thank you for any suggestion and for your patience!
*************************
Activist and author Lynne Twist (2017) has noted three toxic myths of modern society, views that are widely held, yet not just inaccurate – but lethally so: 1) scarcity: there is not enough; 2) more is better; and 3) that’s just the way it is. (...)
As I heard those words she spoke during a wellness seminar where we were both teaching in Costa Rica, the lessons from another citizen of that courageous and innovative country, Christina Figueres, along with her colleague, Tom Rivet-Carnac, reverberated in my mind. (...)
Three mental attitudes or mindsets, in their view, are needed to help humanity achieve the needed practical steps to reverse climate change: 1) optimism; 2) abundance; and 3) regeneration. Finding the consilience between their two approaches, we can see that: a) with optimism we can see options that were not initially in view and regain a sense of hope and a practical path with purpose; b) with the mindset that the world, with reciprocal ways of being with nature, can be both sufficient and filled with abundance; we can then c) release our approach from sustaining a growth-at-all-costs goal to one of regeneration, and then liberate a built-in reciprocity of how we consume and produce on our planet.
If we come to realize these three dimensions of our overall mindset (which I couldn’t help placing into the acronym, OAR), we can row our boat with optimism, abundance, and regeneration down the river of integration; the flow of harmony in the world. In this perspective, we become grateful for life. *** Life echoes in these reverberant, consilient ways *** when we open to its mysteries and the reality of the often-invisible threads that weave us together in our intraconnected wholeness
