Oxytocin and Sensuality in Reiki

Most people think of Reiki as hands and energy. That is not wrong. But something is missing. The deepest transformations do not happen because someone has mastered the right technique. They happen because two people allow each other to truly be felt. This is not mysticism. This is biochemistry. And the molecule at the centre of it all has a name: oxytocin.

No one in the Reiki world talks about this. In the Shingon tradition it has been understood for centuries what happens when the encounter between two beings takes place with open senses — something profound is set in motion. Modern neuroscience can now measure what the old tradition always knew.

In over twenty-five years of practice I have watched this again and again: when the sensory sympathy between giver and receiver rises, the quality of the whole experience rises with it. Not only does energetic perception become finer. Empathy increases. The capacity to feel the needs of another person becomes more precise. This is no accident. Behind it stands a hormone, a brain region, and a principle that places sensuality at the centre of spiritual practice.

Oxytocin — the alchemical elixir of closeness 触

Oxytocin is the bonding hormone. It is produced in the pituitary gland and released during sensory exchange. When cuddling. When holding hands. When kissing. With every form of touch tied to trust and closeness.

What oxytocin does in the body reads like a wish list: it reduces cortisol, the stress hormone. It works as a stress-killer by quieting the amygdala — the brain's fear centre. It stimulates social bonding. It increases trust. It strengthens the feeling of being in love, raises motivation, and supports positive thinking. And it improves the ability to recognise and read facial expressions.

This is not esoteric speculation. These are findings from neurobiology. And they explain something I have watched in hundreds of Reiki sessions: the supportive effects of Reiki rise as the sensory sympathy between both people rises. Not only does energetic perception grow — empathy, the capacity to feel another's needs, becomes more intense too.

In essence, oxytocin is the biochemical equivalent of what the alchemical tradition called the "elixir" — a substance that transforms. Not added from outside, but produced by the body itself. Set in motion by the simplest and at the same time most powerful of all human acts: the touch of another being.

The insula — where empathy and sensuality meet 脳

There is a region of the brain as small as a two-euro coin — and as powerful as almost any other. It is called the insula, the insular cortex. And it is the neuroanatomical proof that empathy and sensuality are not opposites but siblings.

The insula is responsible for: taste and smell in connection with preference. The fulfilment of genuine needs. Emotional evaluation. The inner clock. And — the decisive point — for empathy, sensuality, sudden insight, and the capacity to distinguish one's own needs from those of others.

Read that again. Empathy and sensuality live in the same brain region. Not coincidentally side by side. Functionally interwoven. The capacity to feel another person — to perceive their pain without suffering yourself — is neurologically bound to the same structure as the capacity for sensory perception.

For Reiki practice this means something fundamental: anyone who suppresses their sensuality suppresses their empathic perception too. Anyone who opens the senses opens the channel to empathy as well. This is not a philosophical interpretation. This is neuroanatomy.

Add the mirror neurons — nerve cells that do not distinguish between performing an action and observing the same action in another person. When you see someone in pain, the same neurons fire as in your own pain — dampened, but real. This is the neurological basis of empathy. And it explains why Byosen — the perception of energetic imbalance during the laying on of hands — is no esoteric wish-thinking, but a function of the human nervous system.

The connection between insula, mirror neurons, and the energy centres is remarkable: it points to an axis linking the 2nd chakra (sensuality), the 4th chakra (empathy, compassion), the 5th chakra (expression, communication), and the 6th chakra (intuition, insight). Not as theory — as measurable function of the brain.

The pituitary and the sixth chakra 腺

The pituitary gland is barely larger than a pea. But it is the control centre of the hormonal system. And it sits exactly where the esoteric tradition has placed the 6th chakra for thousands of years: behind the centre of the forehead, at the floor of the midbrain.

The pituitary releases hormones that shape personality. Among them stress-reducing, sensuality-supporting oxytocin. In esoteric correspondence, the pituitary is linked with the Moon (calming, receptive) and Jupiter (optimistic, expansive). The mapping is old — but it aligns strikingly well with what modern endocrinology knows about the gland's functions.

The link for practice: through specific practices in Shingon Reiki, the sensuality function of the pituitary can be addressed via the 6th chakra. Empathy, sensory perception, and the activity of the mirror neurons can deepen as a result. The Siddham syllable Hrih and Senju Kannon — the Thousand-Armed Bodhisattva of Compassion — are connected with this practice.

The concrete steps of this practice belong in the space of the live events — they are transmitted in direct encounter, not through text. But the principle matters: there is a biochemical and a spiritual axis that runs from the pituitary through the hormonal system into empathic perception. And this axis can be activated through practice.

What if I fall in love during a Reiki session? 愛

The question is rarely asked aloud. But it occupies many who practise Reiki. The answer is simple: it can happen. And it is not a problem — as long as you understand what is going on.

Both the receiver and the giver can experience a feeling of being in love during a Reiki session. Falling in love brings a hormonal release that supports sensuality and longing. This is biological. This is human. This is no mistake.

The receiver can fall in love when their need to be understood and accepted is met by the practitioner. The giver can fall in love when they project qualities onto the receiver, or when the presence of the other person triggers attraction. And there is a third variant: the feeling of being in love can "jump" through empathy — from one to the other.

What matters: being in love is mostly a mixture of secondary feelings and hormones — sympathy, attraction, and sense-based sensations work together. As long as the practitioner knows this and handles it constructively — always with the well-being of the receiver as priority — there is nothing wrong with it.

The decisive thing is not whether feelings arise. Feelings always arise. The decisive thing is how they are met. In Shingon Reiki the senses are not numbed — they are refined. And refinement also means: the capacity to distinguish your own feelings from those carried over. This is one of the very functions of the insula.

Breaking the taboo — why feeling deserves no ban 禁

Now it gets uncomfortable. Because in many spiritual traditions — and especially in Western Reiki schools — it is taught that one must feel nothing during a session. The senses should be suppressed. One should be "neutral." One should not be moved by what is happening.

This is exactly wrong.

Suppression of sensuality is not supportive, because the receiver notices it consciously or unconsciously. A practitioner who freezes their own aliveness radiates exactly that: coldness, distance. And this can dampen the mood and impede the activation of self-regulation.

It is the open senses that make transformation possible. Change does not happen in spite of sensuality — it happens through it.

Here is the architecture behind it: the sense of the 6th chakra — intuition, insight, the recognition of the hidden — meets the sensuality of the 2nd chakra — sensation, aliveness, bodily feeling — and they merge in the love of the 4th chakra. Heart, belly, and forehead form an axis. This is not theory. This is the architecture through which deep transformation works.

In the Shingon tradition this principle is embodied by Aizen Myōō 愛染明王 — the Wisdom King of Love. Aizen Myōō stands for the truth that passion and wisdom are not opposites but two sides of the same force. His face is wrathful — not because passion is dangerous, but because it is powerful and demands mindfulness. His body is red — the colour of fire, of transformation, of life.

This has nothing to do with Neo-Tantra. Aizen Myōō stands in an authentic transmission lineage of esoteric Buddhism that reaches back over 1,200 years. He is venerated in the Shingon temples of Japan to this day — not as a symbol, but as a living force. And his message is clear: anyone who banishes sensuality from spiritual practice banishes half of life.

Transforming beliefs and fears of closeness 転

Out of everything described so far comes a set of limiting beliefs that can be recognised and transformed. These beliefs sit deep. They were not consciously chosen — they were taken on. From upbringing, from religious imprinting, from fear.

"I am not allowed to feel." "Sensuality is unprofessional." "I could lose control." "Closeness is dangerous." "If I open, I will be hurt." "Spiritual practice must be cool and distant."

These are not truths. These are programmings. And programmings can be transformed. That is one of the paths Shingon Reiki offers: the possibility of recognising limiting beliefs and dissolving them through practice — not through analysis, but through experience. Through touch. Through encounter. Through the controlled allowing of what is.

Fears of closeness are no weakness here. They are protective responses that were once meaningful. But they can age. And when they age, they become prisons. The Buddhist body practice in Shingon Reiki offers a frame in which these fears can be touched with mindfulness and respect — not to break them, but to transform them.

Shingon Reiki is for people who are alive. Who want to feel. Who do not see sensuality as an obstacle on the spiritual path, but as its most powerful force. Not a sterile energy technique — but a living, breathing, feeling practice.
