1. Reading:

asutorarutai (astral body)

2. Meaning

• A vessel for emotions and imagination: It is a more subtle, energetic "second body" believed to exist apart from the physical body we possess. It is considered a realm that primarily governs human emotions, passions, desires, and imagination, and is also said to play the role of a "mirror" that reflects one's inner self.

• A "starry" body: The word "astral" means "of the stars." Therefore, this body is said to be composed of the light or energy of the stars, or to be a body strongly influenced by the stars (a sidereal body).

• An intermediate vehicle: It is believed that during sleep, meditation, or phenomena known as "out-of-body experiences," this astral body separates from the physical body and functions as a "vehicle" for traveling through a non-material dimension called the "astral plane."

• Aspect as a working term:Apart from these paranormal explanations, it is also positioned as a "working term" or "expedient concept" for objectively describing, examining, and managing raw inner experiences and strong emotional movements without immediately confusing them with reality.

3. Etymology and Origin

• The etymology is the Latin astrālis (of the stars), which lies behind the Greek ástron (star).

• This concept did not originate from a single primary source, but is an integration of multiple ideas that evolved over time.

  • Ancient Roots: Philosophers of Neoplatonism in ancient Greece held the belief that when a soul descends through the celestial spheres to be born on Earth, it acquires a 'vehicle of the soul' (in Greek, ochēma) that carries the properties of each celestial body as it inhabits the physical body.

  • Renaissance (Paracelsus): The 16th-century physician Paracelsus taught that the universe (macrocosm) and the human being (microcosm) correspond to one another (in works such as 'Paramirum'), and argued that in addition to a material body, humans possess a 'sidereal body' (corpus sidereum) that is influenced by the stars.

  • Modern Era (Éliphas Lévi): The 19th-century French occultist Éliphas Lévi referred to the cosmic energy that serves as the medium for all things as 'astral light' (lumière astrale) in his major work, 'Dogma and Ritual of High Magic' (1854–1856), defining it as the principle behind psychic phenomena and magic.

  • Modern Era (Popularization by Theosophy): This concept became widely popularized by the 'Theosophy' movement founded in the late 19th century by H.P. Blavatsky and others. Subsequently, detailed systems were explained in works such as C.W. Leadbeater's 'The Astral Plane' (1895) and Annie Besant's 'Man and His Bodies' (1896), establishing it as a common language in Western occult thought.

4. Synonyms

• Subtle body: A general term used primarily in Indian philosophy for non-material bodies, including the astral body; it is a more comprehensive concept.

• Etheric body: Sometimes distinguished from the astral body as the layer closest to the physical body, acting as a 'blueprint' through which life energy (prana) flows.

• Astral body / Dream body: Terms often linked to personal experience reports, known by the phrase 'out-of-body experience.' While the astral body has a philosophical background, these terms tend to focus on the phenomenal aspect.

• Doppelgänger: A folkloric concept that carries nuances similar to a "double" or "living ghost" that appears independently of the person's will, often considered an omen of misfortune.

5. Case Studies

• Fantasy Literature (H.P. Lovecraft): The novella 'The Shadow Out of Time' (1936) is an example where the theme of consciousness transcending space and time is dramatized in a way that resonates with astral projection. In the story, it is revealed that the protagonist's consciousness left his body to exchange minds with an ancient spiritual entity.

• Film (Doctor Strange): In the Marvel film 'Doctor Strange' (2016), the protagonist's soul is pushed out of his body by his master of magic, allowing him to master the sensation of his consciousness flying freely. Visualized as a translucent, glowing humanoid, the astral body served as a powerful device to express the potential for consciousness to transcend the limitations of the physical body, dramatically increasing public awareness of this concept.

• Film (The Matrix): In the film 'The Matrix' (1999), the protagonist Neo releases his consciousness as a virtual reality (digital avatar) to fight beyond the laws of physics. This structurally aligns with the concept of the astral body operating in a non-material dimension. His awakening to the power to rewrite even the laws of the material world can be interpreted as a modern reimagining of the mystical theme that transformations in the astral realm influence the material world.

• Comparative Religious Studies (Application as a Thinking Model): The astral body also functions as an excellent "thinking model" for comparing and considering the human transformation process across different religious systems.
  Christian theology has stages of "justification"(declaration of salvation),"sanctification"(the process of internal transformation throughout life),"glorification"(the perfected glorious body). Since the astral body governs "emotion and consciousness," it corresponds precisely to this "field (=intermediate body)"as a place where the internal transformation process of "sanctification" occurs.Similarly, in the Buddhist "Trikaya" (Three Bodies), between the "Nirmanakaya" (historical body) and the "Dharmakaya" (ultimate truth), there exists the glorious
  "Sambhogakaya"obtained as a result of spiritual practice. This "Sambhogakaya" can functionally correspond to the glorious body of "glorification"as a "perfected spiritual body."Thus, the astral body can be structurally and brilliantly positioned as an "intermediate body" that carries the process of transformation (i.e., sanctification) from the material "Nirmanakaya" to this "Sambhogakaya".

6. Contemporary Significance

• Source of Creation and Imagination: It continues to provide effective ideas for settings in stories such as fantasy and science fiction, allowing characters to act beyond the laws of physics.

• Metaphor for Self-Awareness: It functions as a rich metaphor for expressing states like "one's mind is not here" or perspectives for objectively re-examining oneself (metacognition).

• Framework for Understanding Extraordinary Experiences: It serves as a cultural "vocabulary" for individuals to understand and explain subjective experiences that remain scientifically unexplained, such as near-death experiences or lucid dreaming.

• Reconsidering Identity in the Digital Age: An "avatar" in VR or metaverse spaces functions like a modern version of the astral body as "another self" separated from the physical body, offering a "new playground" to explore the multiplicity of self-identity.

• Organizational operations and mental hygiene: In situations where strong subjective experiences disrupt decision-making, it functions as a "scaffold" to objectify those experiences as "internal phenomena" and to handle safety procedures and verification procedures separately.

• Exploring universal models in comparative thought: The concept of an "intermediate body" like the astral body is found across cultures and eras. Japan's "Ichirei Shikon" (one spirit, four souls), the "Pancha Kosha" (five sheaths) theory of Indian philosophy, and the hierarchical view of the soul in Jewish mysticism, Kabbalah, also share similar structures. These can be considered universal "maps of consciousness" created by humans to understand, objectively grasp, manage, and transform their own complex inner selves (emotions, reason, and instincts).

7. Conclusion

The astral body is "another body" rooted in the metaphor of the stars, and it is an intellectual compass inherited from ancient times to explore the multi-layered possibilities of ourselves that transcend the constraints of the physical body.
Why not start practicing today by using this term not as a foundation, but as a scaffold for work, to safely translate experiences into words?
