Hi, Risper Ouma Lisa Anyango,
Thank you for your question!
To help me interpret your question, I looked up "distill" in the dictionary, and this seemed to me to be the most result: "extract the essential meaning or most important aspects of".
So the question for me is then: "If I could extract the essential meaning or most important aspects of life into one lesson, what would it be?"
I think Alan Watts may have answered that question the best in my opinion. He said, "The meaning of life is just to be alive. It is so plain and so obvious and so simple. And yet, everybody rushes around in a great panic as if it were necessary to achieve something beyond themselves."
Another relevant quote by Alan Watts is this one I posted on Twitter (a.k.a. X).
One way of re-wording that might be to interpret Alan Watts as saying the meaning of life, or lesson/teaching to follow, is to be more present in your unique present, in a deeply accepting, grateful, and free-spirited way such that you have invincible inner peace (a.k.a. true happiness or even nirvana) making sure that you absolutely do not at all see happiness (a.k.a. inner peace) as something that only exists in the future as a potentiality bought through hopeful suffering in the present. This comes in part from realizing that (1) time isn't real, that (2) objective simultaneity doesn't exist, but that yet (3) presence(s), namely conscious presence(s), do exist, in one sense in the plural of infinite conscious presences (plural) scattered throughout all of spacetime including all of what you might otherwise relativistically and subjectively see as the distant past or the distant future. However, in another sense, as my book teaches, all of these conscious presences are really one. It's like a singular omnipresent cross-eyed presence. Not omnipresent across all of space, because neither space nor time are fundamentally real, but rather omnipresent across all of spacetime.
It's analogous to a single human brain with multiple personality disorder, or like a single human brain having a sleeping dream at night with a dinner party full of guests having really interesting conversations or arguments and debates, but the single human brain is the whole 4D universe of timeless spaceless spacetime, including all what you see as the distant past and far future. When you have a sleeping dream at night with big dinner party and look across the big table at someone else who seems so far away, how far away is that other end of the table really? If all exists in a singular mind, how big is that mind? In one way it's infinitely big and spacious and subdividable, but in another way the furthest distance you can imagine is effectively nothing because separation and distance are dreamy illusions. This also is connected concept of the Two Yous: One of the two yous is one of infinite conscious subjects scattered throughout objectively timeless spaceless spacetime. In the sense of the other one of the two yous, there are no others and rather all others are just other yous, or more of you; it's all the same one being/consciousness/thing wearing all those different outfits, such as 40-year-old Scott (one of our infinite outfits), and 20-year-old Scott (a different one of our infinite outfits), and Scott's 13-year-old son Tristen (yet another of our infinite outfits). We are one, but we have infinite outfits.
For more on that concept of the logically undeniable oneness of all conscious being(s), please read the following topic of mine:
The lion & the antelope share a spirit. Even your worst enemy is but a friend—you yourself in fact—in playful disguise.
The second question for me is how would applying the above lesson change my experiences and/or someone's daily experiences.
I think it gives me, and would give anyone who applies it by following the teachings of my book, invincible free-spirited inner peace (a.k.a. consistent true happiness). Ironically, realizing that you don't need money, wealth, or material or external success to be happy tends to lead one to great external success, be that in terms of money, sports, fitness, fame, or whatever it is for them. Whatever goal you might be running towards, you tend to run much further when you are happy and in the long run you tend to utterly beat any unhappy competition. Because they are unhappy when they are running, they tend to say "this sucks" and stop. Because they are always chasing greener grass in the delusion that happiness exists only as potential in the future not the repent, and depends on reaching greener grass in the future, rather than being more acceptingly and lovingly present in one's present, the unhappy person tends to just run in circles and ultimately get nowhere. They just keep going from side to side, always chasing the greener grass on the other side, in any endless unhappy cycle.
