Lumi refers to a state of higher consciousness associated with entities possessing an aura and core that exude a luminous energy. These entities, known as lumini, include angelic beings, ascended masters, and spirit guides, characterized by their ethereal nature, profound spiritual awareness, and connection to the divine. Lumi encompasses concepts like illumination and spiritual awakening, and practices such as meditation and crystal healing can enhance this luminescence. Organizations foster lumini development, and related entities like the Higher Self and Guardians play significant roles in this journey.
