That High Victorian poet of doubt and loneliness Matthew Arnold might seem increasingly remote to some modern sensibilities, but he can still chuck out a line to stop you in your tracks. (Arnold's capitals and italics, btw.)
"YES! in the sea of life enisl’d,
With echoing straits between us thrown,
Dotting the shoreless watery wild,
We mortal millions live alone.
The islands feel the enclasping flow,
And then their endless bounds they know."
We're back where we live now, a long way from where we've been.
From this:
to this:
It's good to settle back, readjust the colour palette, season and time of day, re-engage with family and good friends in the UK.
But we are geographically separated from some people we wish we were a lot closer to; there are "echoing straits between us thrown."
The pain of geograhical separation is mediated by electronic non-distance. Thanks to Saint Berners-Lee we can talk and see over vast expanses of space and time. You can't throw your arms round a Skype or FaceTime screen, but they sure help. Passenger aircraft fly at not much below the speed of sound. Those we love are - in theory - only a day away.
Keats wrote in a letter of the importance of what he called "Negative Capability: that is when man is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason."
The map on the seat-back set in front of me showed something schematic, unreal:
In this huge aluminium tube, am I really where the little white plane says I am? Are those I want closer to me really so far away? What is geography to the workings of the heart?
I'm finding big paradoxes here.
There is only one ocean, whether it's brilliant azure or delicate blue-greys.
Meditation can create a sense of oneness, unity with both the azure and the blue-grey, with them there and us here.
We can agree with Keats, and say further that living with paradox is an essential part of freedom, of living in the now not in the land of "back then" or "ooo er, whatever next.."
Yet there still lies between us "the unplumbed, salt, estranging sea."
The internet cannot entirely gainsay the Indian Ocean.

This is an oceanic coast, a continental coast. Nothing much between here and South Africa. Our more constrained and limited British seas can also cut up rough and nasty. So is it imagination, and/or knowledge, that makes the difference? Because this feels nothing like the seacoasts at home. Perhaps it’s an endlessly variable combination of light, colour, sound that I pick up in each case, or maybe it's just because I know the fact of difference. Either way, it feels very different from “home.”
Yet there is really only one ocean. On the whole planet, apart from inland seas (aka vast lakes) all oceans and seas are joined, are one. And the old mind-trick of turning a good-quality globe so that Australia is bottom left and you are looking at the Pacific reminds us that mostly, the planet is oceans and seas.
We often allocate human moods to the ocean, as we do to God/gods. They can be merciful, wrathful, gentle meek and mild. The ocean we can call angry, gentle, and so on. It’s not, of course. It is only and purely - the ocean.
Each wave is a fast-moving, continually changing, unique phenomenon, dying right in front of me and being drawn back and resumed.
The ocean is merely and entirely doing what it has done, with endless variations, for millions upon millions of years, before there were any people of any sort to watch it. Do I create each wave in front of me every time I look at it?
Are today’s waves two or three metres high? Hey, this next one must be 3.5 metres...That’s not what yields insight, though it might help me keep my trousers dry.
Maybe I can just be with it, leaving aside analysis and measurement.
And yet, if you just contemplate for a moment the impossibly complex set of dynamic systems - tide; winds here and hundreds of miles out to sea; currents; salinity and other chemistry; air and water temperature; gravity, phases of the moon - the self-sustaining systems that create this particular breaking wave, which resembles the one before it and the one after it but is unique.
If I add that to what I can see and here in front of me, I can feel a sense of awe (in the old and strong sense), presentmomentness, wholeness, identity with the planet and its workings that I’m happy to call sacred, provided you don't start lugging in meanings still adhering to a Rock of Ages, Cleft for Me, etc. (Well, you can if you wish, it's up to you, but that's not what I'm trying to get at here.)
For me, anthropomorphic deities don’t work, and the ocean is not wrathful. It is other than me, indifferent, total. Powerful beyond imagining, yes. Impossibly complex and beautiful, yes, with a beauty that goes much deeper than pretty or scenic. It’s in the curve of the wave as is crumples and blues into white that I find a sacred wholeness to sit with for a while.
