Spiritual fluid is one of the central concepts of Spiritism and appears prominently in the works of Allan Kardec, especially in Genesis. Understanding what fluids are and how they operate is essential to grasp mediumship, healing phenomena, spirit passes, and even the formation of the perispirit.

But what exactly did Kardec mean by “fluid”? How is it different from energy? And in what ways can these invisible elements influence our health, our thoughts, and our spiritual connections?

In this article, we’ll dive deep into Kardec’s vision of fluids, bringing updated interpretations, practical examples, and reflections that may change the way you understand spirituality.

What Is Spiritual Fluid?

In Spiritism, the term fluid refers to subtle substances that permeate the universe and participate in countless spiritual phenomena. These fluids are used by spirits to act upon matter, influence organic life, shape the perispirit, and interact with incarnated beings.

Kardec explained that the term should not be confused with “energy.” While energy is a property of matter, fluid is described as a subtle type of matter not yet identified by physical science.

In short:

• Energy = property of matter.
• Fluid = subtle matter, still unknown to science.

This distinction is crucial to avoid confusion between scientific and spiritual language.

Historical Origins of the Word “Fluid”

Before Kardec, the word “fluid” was already used by science to explain invisible or poorly understood phenomena.

• Middle Ages: epidemics like the Black Plague were thought to be caused by a “pestilent fluid.”
• Ancient physics: fluids described elements capable of moving, penetrating matter, or producing effects, such as electricity, heat, and magnetism.
• Modern science: the term was restricted to liquids and gases.

Kardec, however, gave it a new spiritual meaning, linking it to subtle substances that form the basis of spiritual phenomena.

Universal Cosmic Fluid: The Primordial Matter

According to Kardec, the Universal Cosmic Fluid (UCF) is the primitive elemental matter from which everything originates.

“The universal cosmic fluid is […] the primitive elementary matter, whose modifications and transformations constitute the innumerable variety of bodies in nature.” (Genesis, chap. XIV, item 6)

The UCF is, therefore, the raw material of the universe, infinitely transformable, giving rise to:

• Dense matter (the physical body).
• Subtle matter (the perispirit).
• Different varieties of spiritual fluids.

Just as the atom explains material diversity, the UCF explains diversity in both the spiritual and material planes.

Classification of Fluids in Spiritism

Although Kardec did not create a strict classification, he indicated three main categories:

1. Vital Fluid

• Modification of the UCF that animates living beings.
• Responsible for organic life and the connection between the physical body and the perispirit.
• Renewed constantly through breathing, nutrition, and spiritual influences.

2. Spiritual Fluids

• Manipulated by spirits through thought and will.
• Reflect the moral nature of the sender: higher spirits emit pure fluids, while lower spirits produce dense and disturbing ones.
• Present in mediumistic phenomena, spiritual healing, and fluidic images.

3. Animal or Magnetic Fluid

• Emanates from incarnated beings and can be directed by will.
• Forms the basis of magnetic passes used for healing and balance.
• When enriched with spiritual qualities, it is called “animalized” or “vitalized” fluid.

Fluids and the Perispirit

The perispirit is the fluidic body surrounding the soul, formed from condensations of the UCF adapted to the spirit’s evolutionary stage.

Functions:

• Intermediation: connects the soul to the physical body.
• Sensation: conveys perceptions from the external world to the soul.
• Expression: transmits the soul’s vibrations to the environment and other spirits.

Important: the perispirit does not think or feel on its own. It only reflects the soul’s thoughts and moral qualities.

How Thoughts Influence Fluids

One of Spiritism’s most powerful insights is that thoughts directly affect fluids.

• Elevated thoughts → purify and harmonize fluids.
• Negative thoughts → contaminate and disturb fluids.

That is why prayer, meditation, and practices like the Gospel at Home are essential for improving both the quality of the environment and spiritual health.

Practical Applications

1. Spirit Passes → Transfer of magnetic and spiritual fluids for physical and emotional balance.
2. Mediumistic Meetings → Mediums capture and transmit fluids to enable communication.
3. Gospel at Home → Harmonization of the home’s fluids through prayer and reflection.
4. Spiritual Healing → Benevolent spirits use subtle fluids to assist the sick.

Fluids and Future Science

Kardec was cautious:

• He admitted we do not yet know the chemical composition of fluids.
• He affirmed that one day science will study them, as it did with electricity and magnetism.
• He stressed the moral aspect: our thoughts shape and qualify the fluids we emit.

How to Improve Your Fluids Daily

• Pray and meditate regularly.
• Practice charity: good deeds generate uplifting vibrations.
• Keep your environment clean and harmonious.
• Avoid addictions and excesses that deteriorate vital fluids.
• Cultivate positive thoughts and feelings.

Conclusion

Studying spiritual fluid shows us that the universe is far more dynamic than we imagine. These subtle elements connect body and soul, spirit and matter, humans and nature.

Kardec invites us to realize that, although we still don’t know their exact composition, we already understand one essential fact: fluids respond to thought. For this reason, nurturing noble feelings, sincere prayers, and kind actions remains the best way to purify our spiritual lives.
