The merkaba, a symbol formed by two counter-rotating tetrahedrons, represents the union of light, spirit, and body, primarily focusing on personal development and higher consciousness. It has deep roots in ancient Egyptian and Jewish traditions, believed to aid in meditation and energy work, facilitating healing and protection while enhancing sensory perception and connection to higher realms. The practice of merkaba meditation activates one's energy fields and is seen as a powerful tool for achieving harmony and manifesting one's intentions.
