Psychedelics, Quantum Mechanics and Hyper Reality | Christof Koch & Bernardo Kastrup

Watching Christof Koch evolve over the years has been a masterclass in having the humility to challenge your own deeply-held beliefs and assumptions

Everyone needs a mystical experience.

I discovered many years ago that I was overly sensitive to visual cues in the faces of the listeners I was speaking to. Especially when trying to convey a more complicated concept to someone. By closing my eyes when I talked, my mind suddenly relaxed and I could maintain a coherent stream of consciousness to the intended conclusion. I believe my strong intuitive empathetic nature was overwhelming my senses, and closing my eyes unplugged that part of my brain. It is exciting to discover the same behavior in others. Closing one door opens many others.

I really appreciate that more and more scientists are now openly exploring consciousness and even considering the possibility that Consciousness itself may be the foundation of reality. Many are searching for the brain’s role in how the world is perceived and how this process works. My comment comes from this context, yet from a very different kind of observation. From my own experience, it seems that the brain is not the origin of perception but something the mind has conceptualized in the act of searching for it. The mind builds its sciences and theories through this search, and this process can expand endlessly in every direction. The more we search, the more structures we create. What I have found is that reality cannot be reached through conceptual understanding, but only through direct experience – the experience of the Self as the Self, through the Self within the Self. In this sense, it feels that we are always seeing through the mind rather than through the eyes. The eye and the brain appear as forms through which Consciousness experiences itself as the world, not as their ultimate source.

Gratitude to Dr. Christof Koch, Dr. Bernardo Kastrup, and Hans Busstra for a remarkable conversation. It echoed the Vedic understanding that Vidya includes both tested knowledge and direct realizatdion….forgotten science where truth is known by experience (anubhava), not inference alone. Your dialogue reminded me that some insights feel ancient because they are….precise, universal, and waiting for modern science to remember how to listen.

I am a massage therapist and the longer i practice the more it becomes clear that the body is one thing - not the parts we pull apart to understand it’s function and dysfunction. That practical understanding also points to the whole of my experience and nature as being one thing too. We pull ourselves apart from nature to understand it and it’s reality is that all are not separated things - only one.

I would just like to take a moment to not only show my appreciation for the thoughtfulness of the content but also the thoughtfulness of the lighting of these videos, pleasing to the eye, and pleasing to the mind. Beautiful.

In 2006, Koch wrote an essay in Nature, _Quantum mechanics in the brain,_ in which he concluded "there is little reason to appeal to quantum mechanics to explain higher brain functions including consciousness." How we've come full circle from the days of Eccles. I remember as an undergraduate and then later as a graduate student being ridiculed at the "ridiculousness" of giving any consideration to Penrose or Eccles, who historically was the first to consider quantum mechanics being needed to explain brain processes. And now the empirical evidence exists and growing that the warm wetware of the brain can indeed exploit quantum mechanical phenomena. It is sad that Penrose's main thesis seems seldom understood: the man was not arguing that quantum mechanics is responsible for consciousness but _involved_ and that there is a deeper and as of yet not understood theory to explain consciousness that is in addition fundamentally _non-computational._

Dag Hans (ik ben Nederlander) I'm new to this channel. I've had various spiritual experiences (without drugs) in my life and these have given me insight into many things, although it wasn't always immediate clear because people still have certain beliefs so some things took time. What I want to say briefly is that we humans have language to tell each other things, but books and talking fall short because it's about experiencing. You can read books about cycling, but you have to get on the bike; that's experiencing. Every person has access to experience because, in essence, we are consciousness. We consist of matter, which consists of molecules and atoms, but descend further into the very smallest and only energy or consciousness remains, and that's what the entire universe consists of; everything is energy. There, one enters the realm of quantum physics, where there is no position, time, or space. Time and space only exist in our universe because everything has a position and everything seems separate, but at that other level everything is connected, always and everywhere, even though many people are unaware of this.

First, thank you to Essentia Foundation and everyone involved in creating this conversation. Watching Koch and Kastrup navigate these questions with such rigor and openness is genuinely valuable—especially Koch's willingness to let his mystical experience reshape his thinking without abandoning scientific standards. Koch mentions his ontological shock at 67, suddenly feeling "Oh my god, I've been wrong—it's all mental, it's all phenomenal." I find this fascinating because I think the real revelation isn't that reality is fundamentally mental versus physical, but something subtler: we've been looking in the wrong direction the entire time. When Koch describes his experience of "hyperreality"—consciousness more real than everyday awareness—there's an immediate interpretive move many people make (including Koch himself): this must be accessing some cosmic consciousness, some universal mind beyond the individual self. But what if that's backwards? What if these experiences aren't revealing something *out there* but something *already here*—something we've been carrying since before we had language to describe it? Think about the first thousand days of human development, from conception through early infancy. During this period, consciousness exists without ego boundaries, without the conceptual filters that later define "normal" adult awareness. This isn't primitive or undeveloped consciousness—it's consciousness prior to its fragmentation into subject/object duality. The infant doesn't experience separation between self and world because that separation hasn't been constructed yet. Psychedelics don't transport us to alternate dimensions or cosmic mind-spaces. They temporarily dissolve the structures that developed *after* that early period—the default mode network, the narrative self, the whole apparatus of symbolic thought. What feels like encountering "universal consciousness" might actually be returning to a mode of being we all inhabited before ego crystallization. Not discovering something new, but temporarily recovering something old. This matters for how we interpret these experiences. The universals that Benny Shannon documented—jungles, serpentine architectures, geometric patterns—don't require metaphysical multiworlds to explain. They might simply reflect common features of how human consciousness organizes itself when the usual constraints are lifted. We all have similar neurological architecture; of course we'd visit similar phenomenological territories when those systems are disrupted in similar ways. Koch rightly resists Bernardo's many-worlds interpretation of quantum mechanics, saying we shouldn't mistake "convenient fictions" for ontology. But I think the same caution applies to mystical experiences: the *feeling* of cosmic consciousness doesn't necessarily mean we've accessed literal cosmic consciousness. It might mean we've accessed pre-egoic consciousness—which feels boundless because it hasn't yet learned boundaries. And here's why this reframing matters: the journey from conception to death is *already* long enough. Profoundly long. You get decades of rich phenomenological experience, the entire arc of a human life, from that first undifferentiated awareness through ego formation and (if you're lucky) eventual ego dissolution at death. That's not a brief spark that needs inflating into eternal recycling or cosmic merging. It's a complete story. The trillion-year reincarnation cycles or eternal heavens/hells that various traditions promise? Those always felt to me like failure to appreciate the magnitude of what we already have. One human lifetime—*really experienced*, with full presence—is cosmically significant without needing supplement. So when Koch talks about exploring these states scientifically, I'm fully supportive. But let's not confuse exploring the architecture of our *own* consciousness with mapping alternate realities. The palace with many rooms that Koch describes? It's inside. It's been inside since before you could speak. Psychedelics just temporarily unlock doors that socialization closed. That's enough. That's actually kind of miraculous.
