I find it troubling when humans high five each other about how awesome we are. We still have humans who hold dangerous and irrational beliefs that cause the planet harm, including the future of life on the planet. I've seen fervent religious people think their fervor equates to some high level of consciousness when it's evident that they are just absorbed in an irrational framework of belief. From what I have observed it is evident that those who feel less a motivation to believe in some framework are closer to some sort of conscious awareness. I say this because believers get absorbed and lost in their head full of concepts whereas those with fewer beliefs are more aware of their raw conscious state. Fewer beliefs means less interference to wisdom and understanding.
A more advanced mind will realize the self is just a being on the planet, like any other animal, and can think about itself in ways that confuses itself, unlike other animals. Looking for an answer about "who the self is" only suggests to the self there is an answer. Does this self even wonder WHY its asking questions that don't have an answer? No. We evolved with a high degree of fear and anxiety, and our capacity for rational thinking can exacerbate fears and anxiety to a degree that we seek to create or adopt a framework of belief to offset these emotions.
I suggest it's better to understand how our brains work and face the fears head on, and deal with these emotions as disciplined and wise adults. It's easy to believe. It's hard to develop discipline and wisdom.
But we are an incredible species, and it is our consciousness that makes us so. That our capacity for destruction and cruelty is as awe inspiring as any of our other qualities, is of course undeniable.
I don’t think it’s belief, or the lack of it, that is the cause of all or most of our problems; and I would suggest that the instinct to divide human beings into categories, such as believers and non believers, is a function of our destructive instincts, not our constructive ones. Pointing the finger of judgement at one group, while ascribing all that’s good to another, helps no one imo.
As regards the self, perhaps we should define our terms here. For me, there is the lower self, the ego, and also a higher self. We need always to guard against the ego, that false self which tells us we are separate, alone, that we are right to be afraid, that we will never be satisfied.
As for the higher self, I see it as something like this description from verse 8 of the Isha Upanishad;
The Self is everywhere. Bright is the Self,
Indivisible, untouched by sin, wise,
Immanent and transcendent. He it is
Who holds the cosmos together.
Unless we learn, collectively and individually, to elevate our consciousness from the false, egotistical mind to the enlightened, exalted mind, I don’t see much of a future for our species; we need to make that evolutionary leap forward and we need to make it soon.
