Auras

Auras are commonly described as luminous energetic fields or fields of subtle energy that some believe surround the human body. While they are a staple in various spiritual and metaphysical traditions, they are not generally recognized by mainstream science or medicine. Nonetheless, some experience and/or witness them. 

My phrasing here may seem less concrete or cut and dry - and that is because, for the most part, someone who does experience and/or witness auras does not necessarily witness them in the same respect that another does. One person may see them (quite literally) with their own eyes or with their second sight, third eye, clear sight, etc. Another person could very well experience them as a feeling, an intuitive nudge, or something else, in a literal or figurative sense. On the other hand,  auras are not -fixed- states of being. There is a nuance and an ebb and flow to them - each unique to the individual, the moment, environment, etc.

That aside, here is a breakdown of what auras are, where the concept comes from, and how they are viewed across different practices:

Origins and Cultural Context

Historical Roots: The concept draws inspiration from ancient traditions, including traditional Indian medicine and philosophy (where they relate to prana, chakras, and the subtle body).

Theosophy & Modern Views: The modern popularization of auras in Western culture largely grew out of the Theosophical movement in the late 19th and early 20th centuries, which sought to blend Eastern spiritual concepts with Western esoteric thought.

Common Beliefs and Meanings

In contemporary spiritual practices, auras are often believed to:

Reflect States: Change in color, intensity, or size depending on a person's emotional, physical, or spiritual state. These states can change slowly or rapidly, and can largely depend on the individual who is "looking" at them.

Have Specific Colors: Various colors (such as red, blue, green, or yellow) are often associated with different personality traits, moods, or chakra centers.

Interact: Blend or clash when people are near one another, often referred to as "vibes" or energy. Vibes is a more modern term derived from the shorthand for "vibration". 

Aura Color Overview

Here is a quick overview of all the aura colors, summarizing their core themes and meanings in traditional metaphysical practices:

Red: Vitality, physical energy, passion, action, and survival (tied to the root chakra).

Orange: Creativity, emotional expression, sociability, sensuality, and zest for life (tied to the sacral chakra).

Yellow: Intellect, optimism, analytical thinking, confidence, and playfulness (tied to the solar plexus chakra).

Green: Healing, growth, balance, empathy, and renewal (tied to the heart chakra).

Blue: Communication, calmness, truth, expression, and spiritual depth (tied to the throat and third-eye chakras).

Purple / Violet: Spiritual awareness, intuition, imagination, and mystical insight (tied to the crown chakra).

Pink: Unconditional love, compassion, emotional sensitivity, romance, and nurturing warmth (tied to the heart/higher heart).

White: Purity, spiritual perfection, high vibration, protection, and divine connection (synthesis of all chakras).

Brown / Black: Grounding, physical exhaustion, transition, energetic protection, or deep emotional heaviness.

A little more context is given on the range of colors on the Common Aura Colors and Their Associations page.

Scientific Perspective

Lack of Empirical Evidence: There is no peer-reviewed, -common census- scientific evidence to support the existence of a human aura field or energy that can be visually detected or measured by scientific instruments that the greater scientific community agrees upon.

Synesthesia and Perception: Some neurologists suggest that experiences of seeing auras may be related to synesthesia—a neurological condition where stimulation of one sensory pathway leads to automatic, involuntary experiences in a second sensory pathway (such as "seeing" colors when hearing sounds or looking at people).

Optical Phenomena: Visual artifacts, eye fatigue, or afterimages can also sometimes cause people to perceive glowing outlines around objects or bodies.
