With rising distress in post-industrial culture;
science has been exploring spirituality

There has never been a time in post-industrial global culture where scientists have observed suffering at the scale we are experiencing today.
Rates of addiction, depression, and death by suicide continue to rise at alarming levels.
And, surprisingly, science is beginning to point to a clear, often overlooked solution: spirituality.
This article is inspired by a lecture by Professor Lisa Miller at the Oxford Interfaith Forum, in which she explores the intersection of neuroscience, mental health, and spiritual life.

The generation in distress
We often experience suffering as isolated events: a diagnosis, a loss, a tragedy and so on.
But scientists look at patterns.
And what they are seeing is deeply concerning.
Professor Miller shared that 48% of individuals aged 18–25 in the United States report at least a moderate level of what researchers call “diseases of despair”, a level of distress intense enough to impair functioning and, in many cases, provoke suicidal thoughts.
Her question is simple, but very deep:
“What is in the air, water, or culture that is causing this?”
The missing link: spirituality
Alongside the rise in depression, anxiety, and trauma, researchers have observed another trend:
A steady decline in both personal spirituality and communal faith practices.
As Miller has discovered in over 20 years of research, these two patterns are not unrelated.
In fact, her work suggests that daily spiritual awareness may be one of the most powerful neuroprotective factors against mental illness.
Key pattern observed:
- Up to 80% support in recovery from addiction (DSM-related)
- A 62% reduction in risk-taking behaviours
- Up to 82% lower likelihood of suicide-related outcomes
This isn’t woo woo BS. This is neuroscience, babe!
What is spirituality and what it isn’t:
Let’s clarify something important: spirituality is not the same as religion.
Religion is shaped by your environment, family, culture, geography, tradition, etc.
Spirituality, on the other hand, is something innate. It is the human capacity to seek connection with something greater than oneself, whether that’s God, nature, the universe, or even Goku. No judgment here, pal!
Science doesn’t define spirituality in theological terms, but it can observe its effects.
What spirituality does to the brain
In a landmark study published in JAMA Psychiatry (2014), researchers used structural MRI scans to observe the brains of individuals who sustained a spiritual life over time.
The results were nuts!
People who reported that “their spiritual life is important” and maintained that relationship for over 8 years showed:
- Increased strength in cortical regions
- Enhanced emotional regulation
- Greater resilience to depression
Simplifying it:
Spirituality changes the physical structure of your brain!
And even nicer, there is no single path to it.
Meditation, acts of service, ethical living, contemplation…
Even the pursuit of becoming Bruce Lee or Master Yoda contributes.
The two dimensions of spirituality
From a scientific perspective, spirituality tends to express itself in two main ways:
- Connection to the transcendent
(God, nature, a higher intelligence, or any other sense of unity). - Connection to others
(Seeing ourselves as part of a shared human experience and automatically treating others with more compassion).
When both are present, we begin to understand where we end, and the world begins.
And paradoxically, how deeply connected we all are.
When spirituality was shared
For most of human history, spirituality wasn’t a private, isolated experience.
People used to gather in public squares and open spaces to share, question, and explore different spiritual perspectives together.
These were natural places of dialogue, disagreement, curiosity, and collective meaning-making.
Spirituality was lived in relationships.
Over time, particularly in Western societies, there was a cultural and political shift toward organising spiritual life within designated institutions, such as churches, temples, and other private spaces.
This movement was an attempt to respect diversity and reduce conflict.
But intentionally or not, it also had a negative consequence:
Spirituality became increasingly compartmentalised. What was previously something explored as groups became something practised in private spaces, detached from daily public life and, for many people, slowly abandoned.
When we remove common spaces for spiritual dialogue, we risk underdeveloping what neuroscience now suggests to be a core human capacity.
A culture that weakens the spiritual core
This shift becomes even more visible in modern culture.
In another study mentioned by Lisa, researchers found that adolescents in affluent schools reported higher levels of depression and hopelessness than those in less privileged environments.
Why? Because of what was being valued.
Among girls, the main predictors of popularity were:
- Weight
- Relational aggression (“mean girls”)
And among boys:
- Substance use
- Sexual conquest (not connections, only numbers)
Add to this the isolating effects of social media, and now we get a culture that disconnects people from meaning, replaces belonging with performance and weakens the spiritual core.
That’s a very dangerous combo!
Spirituality, suffering, and post-traumatic growth
Interestingly, suffering can serve as a gateway to spiritual development.
Studies on PTSD and war veterans show a strong correlation between trauma and spiritual growth, often referred to as post-traumatic growth.
But this doesn’t happen automatically.
Researchers identified four key factors:
- Accessing the experience (not avoiding it)
- Putting it into words
- Sharing it with others
- Bringing a sense of meaning or transcendence to it
In other words, pain becomes transformation when it is integrated, shared and addressed.
Achieving awareness vs awakened awareness
There are two fundamental modes of awareness:
Achieving awareness:
- What can I get?
- What is my goal?
- What is my strategy?
Awakened awareness:
- What is life showing me right now?
- What is being asked of me?
- What is unfolding through me?
One is linear, and the other is entirely relational.
And when we learn to move between both, something remarkable happens in our brains:
We build new neural pathways. Bridges between logic, emotion, and meaning.
The frequency of a new life
Professor Miller describes this state as a “wave”.
The same wave is associated with meditation, the wave observed in monks’ brains.
A wave called high-amplitude alpha.
Interestingly, this wave is also present in Schumann’s Resonance, the Earth’s natural electromagnetic vibration.
Poetic, isn’t it, my friend?
But also scientific and very measurable!
Concept of Eden as a state of awareness, not a place
Miller offers a scientific reinterpretation of what she considers Eden:
Eden is not a place per se. It is rather a level of awareness.
A way of being where life is experienced as meaningful, interconnected, and somehow sacred.
Einstein, integration, and the table of knowledge
Before you go, I want to let you know the following Einstein quote, one of my favourite ones:
“A human being is a spatially and temporally limited piece of the whole, what we call the ‘Universe.’ He experiences himself and his feelings as separate from the rest, an optical illusion of his consciousness…”
He is not talking about naive belief. Or rigid logic.
He is talking about spirituality as integration.
Where sceptics, mystics, and scientists sit at the same table and create something entirely innovative.
When times get tough, spiritual people don’t just break. They search, they question, and they expand on the answers.
And in doing so, they begin to tune into a different frequency.
One that heals.
One that connects.
One that genuinely cares. 💛
