Your Nervous System’s Best Investment — Part 4 of 4
By Eva Selhub, MD
Over the past few weeks, we have been exploring how the nervous system, as a living system in constant pursuit of balance, may perform, heal and sustain more effectively when its preferred strategy for achieving that balance is supported rather than overridden. That strategy, as the science increasingly confirms, is love — and more specifically, the physiology of love, the measurable biological state that the nervous system may reach through three distinct but interconnected pathways: social love, self love and spiritual love. Together these form what I call the Love Pyramid — the infrastructure through which the physiology of love becomes not a peak experience to be chased, but a ground state to be cultivated. The question this final piece addresses is perhaps the most practical one: how do you actually build it?

Why the Infrastructure Erodes
Before addressing what to build, it may help to understand why this infrastructure tends to erode — particularly for people who are achieving steadily and may feel they have little reason to question what appears to be working.
The answer lies not in something complex, but rather in a choice — conscious or not — to prioritize the external over the internal. The external world — achievement, recognition, outcome — tends to be measurable and immediately rewarding to the dopaminergic system, while the internal world — the quality of relationships, the relationship one has with oneself, connection to something larger than the immediate goal — tends to be quieter, more difficult to quantify, and rarely announces its absence until the body begins to do so instead.
If you are like many others, it may not be that your three pillars are nonexistent or collapsed, but rather that they lack good funding. Social connection may have gradually become more transactional, self-regard more conditional on performance, and spiritual life — meaning, awe, connection to something beyond the self — deferred until there is more time, which tends not to arrive on its own. As the nervous system reaches out for balance through any remaining open channels, the allostatic load insidiously accumulates. I have seen this time and time again in my practice — someone will say they were fine until such and such happened, and they cannot understand why they cannot get back to where they were. What they may not realize is that the allostatic load was accumulating all along, and that the event did not create the vulnerability but rather revealed it.
The infrastructure may not be gone, but rather, it may simply be underbuilt. And unlike many interventions, building it may require less in the way of additional effort and more in the way of a different quality of attention.

The First Pillar: Social Love
Social love is the experience of genuine connection — giving and receiving, supporting and being supported, belonging to something with other people. It may be the most physiologically immediate of the three pillars, as the oxytocin system responds to touch, eye contact, physical proximity and the felt sense of being genuinely seen by another person, and the ventral vagal pathway responds to the quality of relational contact in real time.
For many people, and particularly for those in leadership or caregiving roles, social love has a dimension that tends to go unexamined: the capacity to receive. Giving — mentoring, supporting, providing — may come more readily, while receiving — asking for help, allowing vulnerability, letting another person’s care actually land — tends to be more difficult, and for many people feels almost counterintuitive. And yet the receiving side matters biologically, as the nervous system may not fully regulate through giving alone.
In practice, building social love may come through paying attention to the quality of the relationships that matter most — through conversations where you are genuinely present, through moments of real acknowledgment, and through the willingness to ask for support when the body is signaling that it needs it. Physiologically, these kinds of relational experiences may shift the autonomic state of the nervous system in ways that research has shown to be measurable and reproducible (Uvnäs-Moberg, Physiology & Behavior, 1998). The Love Response® describes this mechanism in detail — how love in its social form activates the oxytocin system and the ventral vagal pathway, shifting the body into the parasympathetic state where healing, clarity and genuine connection become possible.

The Second Pillar: Self Love
Self love may be the most misunderstood of the three pillars, and perhaps the most consequential, as it is less about self-care in the conventional sense — though rest, nutrition and movement all matter — and more about the quality of the inner relationship: the degree to which the nervous system experiences the self as safe, as enough, and as worthy of being supported.
At the core of the stress response, as we established in piece one, are the beliefs the nervous system holds about manageability — whether the resources available feel sufficient to meet the challenge at hand. Those beliefs tend not to be primarily cognitive, but rather embodied, encoded through early experience and operating largely outside conscious awareness. Someone who performs brilliantly under pressure while quietly carrying a belief that they are never quite enough may be running a stress response that never fully resolves, regardless of what is achieved externally, as achievement may confirm competence while tending not to touch the deeper belief.
Research on self-compassion consistently shows reduced cortisol reactivity, lower inflammatory markers and greater resilience under pressure, compared with more self-critical approaches to difficulty (Neff, Self and Identity, 2003). A nervous system that experiences itself as fundamentally safe and worthy may take risks more freely, tolerate uncertainty more steadily and sustain effort over time in ways that the chronically self-critical system may find more difficult. The Love Response® addresses this directly — the process of uncovering and reprogramming the distorted beliefs that keep the stress response activated and the self-love pillar chronically underfunded.
In practice, self love tends to begin with witnessing — turning attention toward inner experience without immediately evaluating it, noticing sensation, emotion and thought as information rather than as evidence of adequacy or inadequacy, and from that ground allowing compassion to become more available, so that the deeper belief that the self is enough may begin, gradually, to shift.

The Third Pillar: Spiritual Love
Spiritual love is connection to something larger than the individual self. For some people that is a religious or contemplative practice, and for others it is nature, music, art, community, or the direct experience of awe that arrives when the self temporarily dissolves into something vast. What matters biologically is less the form and more the function — the quieting of the default mode network, the reduction of self-referential processing, and the shift into a more expanded state where the nervous system is no longer running the threat narrative and something more spacious may become available.
As the research covered in piece three suggests, even brief experiences of awe may produce measurable reductions in inflammatory markers, increases in vagal tone and shifts in mood that persist well beyond the experience itself (Monroy & Keltner, Perspectives on Psychological Science, 2023), with nature, genuine creative engagement, deep meditation and the kind of human connection that produces the feeling of being part of something beyond oneself all tending to support this shift reliably and accessibly.
Spiritual love may require the most deliberate cultivation, because it tends to ask for something the achievement-oriented mind may resist: a quality of surrender to the present moment, to what is, to something that cannot be controlled or optimized, and it may be precisely in that quality of surrender that a different kind of capacity begins to open.

So What Does This Mean in Practical Terms?
The Love Pyramid tends to be built through the accumulated quality of daily attention — to the relationships that genuinely restore, to the inner voice that either supports or undermines the nervous system’s sense of safety, and to the moments of beauty, connection and awe that are present in any life that is paying attention.
The body whispers before it screams. Your senses are giving you information all the time — about whether you are hungry, whether you are uncomfortable, whether your needs are being met. It takes a willingness to listen and to attune to those signals, to attune to your own needs and to the needs of others, to be fully present with what is, both internally and externally. And it is in that quality of presence — in that place of peace, calm and restoration within — that the conditions for genuine connection and restoration in the external world may begin to emerge. The body is creating those signals constantly, letting us know through the language of stress what it needs and where the balance has been disrupted. The question is, what are you going to do about it?
If this series has landed somewhere real for you, I would be glad to hear where. What did you recognize in yourself, and what are you going to do about it?
