Well, pondering further.....
As I've already said, I see no reason to contrast "doing" with "pondering" as if a choice must needs be made. Those who actually keep the world turning - inventing, developing technology, finding cures or whatever - can also ponder. They do not even have to come to any particular conclusions! Some may prefer them, obviously. Fixed points. They offer a safety of sorts.
“Get out of the armchair and into the lab”, the approach of the neurophilosopher Patricia Churchland in seeking to explain consciousness! Sooner - or later - a "conclusion" will reveal itself. Some would hope so. Anyway, I would always prefer the armchair, but it does not necessarily exclude the lab.
As I see it, Reality itself has no "conclusion". It is infinite potential. Empty of "conclusions" Reality can continue to unfold, ever new. Buddhism speaks of "sunyata" - "emptiness". When I speak of this it is "mumbo jumbo", while Buddhism is simply accused of nihilism. But as I see it (or perhaps, do not see it) Reality, being "empty" is thus able to be all things - potentially. Or as is said in Mahayana Buddhism, "emptiness is form, form is emptiness"; or in a more soteriological context, "nirvana IS samsara". Thus THIS world, the only home we have ever known, is not betrayed for some imagined "other". We can be at home, here, now. The journey is home. Home is the journey; and what will be will be.
All academic mumbo jumbo? Not for me. I have found my own path life-giving. A while ago I asked on a Buddhist Forum:- "In what way does suffering end?" A suitable question, given that the Buddha declared many times: - "I teach this and this alone, suffering and the end of suffering." One guy thought he had cut the thread short with just one blow by quoting some text that sought to describe nirvana and its peace. Me, I was not satisfied. The question remained. Human suffering, including my own, continued to burden me. Every newscast revealed/reveals its depth.
The "answer" I have found is that the loss of loved ones remains, grief remains, pain remains, even that which we call evil; in fact, nothing changes. But we do not have to "suffer". This is not to become unfeeling and callous. It is more to be here for others.
There is an old zen story, of a great master who began each day with a walk through the village. One day he passed a house and heard from inside the wailing of a family who had lost a loved one. The master stepped inside and began to weep with them. One of his students came by, heard the master, went in and said to him:- "Master, you of all people I would have thought would be beyond all this". The master replied:- "It is this that puts me beyond it."
Obviously, potentially, it is not just tears we share. Who knows just what the future holds?
Well, to be honest I have had enough for the moment. For a variety of reasons.
