“Think globally, act locally”
Again this pops up. It’s because I’ve realized there are more dimensions to it than geographical. I think also there are historical dimensions to it. Thinking globally is looking at the global situation and acting locally is applying its implications to your life. But also we can say “Think historically, act in the present”. That is look at the history of things, both the events of the past and the possibilities of the future, because these too have implications on how we are living now.
Maybe we can say “Think globally and historically, act locally and in the present,” except that that is too much of a mouthful and not catchy enough.
Maybe we can say “Think transpersonally, act personally.” It’s nice and short, and encapsualtes the historical/global and local/present; however, people may not be too familiar with the term transpersonal.
I think “think globally, act locally” is good enough. Plenty of people know it, it’s catchy and has been for several decades. But now we know it doesn’t just reach around the globe but also into the past and the future, acknowledging where we have been and where we may be going.

“We don’t inherit the earth from our ancestors we borrow it from our children” David Brower

“Everyone alive is descended from somebody smart enough to survive the past. But you must not worship your ancestors. The sole purpose of your ancestors’ existence was your life. And the sole purpose of your life is your offsprings’.” Stephen Baxter, Mammoth

“The future enters into us in order to transform itself in us, long before it happens.” Rilke

The Ancestors worked for me, they worked to develop and manifest their wisdom; their experiences of the past and visions of the future, that have been past to me, not as a finished product, but as a work in progress. It is now my duty, not to my Ancestors but to my Descendants, to carry on this work, to have a vision of the world, of where it is and where it is going, and be a midwife to the future.

To honour the Ancestors, with thanks I take up the work that they did for the good of me and carry it even further. But to honour the Descendants I must fulfill for them what my Ancestors worked to fulfill for me. It is my Descendants’ expectations that I must live up to, not my Ancestors’, because it is my Descendants that will inhererit all the good and bad legacies of my life, it is they who will have to deal with the consequences or opportunites that I have to give to them, not my Ancestors.

My Ancestors; parents, grandparents, great grandparents etc, are answerable to me as though I were a boss to them. So I ask them, “I am your future incarnated, what can you say you’ve done for me, the Descendants and for the future of the world?”
And in turn, my Descendants will ask the same of me and I aspire to reach a point where I can rightfully say “I have done well for you my Descendants, now do well for your Descendants.”
