Power, wisdom and love
The trinity of the threefold flame—Power representing the Father, Wisdom the Son, and Love the Holy Spirit. The balanced manifestation of these God-qualities in and as the flame within the heart is the prerequisite to personal Christhood.
Attributes of the Hindu conception of the Trinity as (1) Brahma, the Creator, (2) Vishnu, the Preserver, and (3) Shiva, the Destroyer of evil/Deliverer of souls.
According to the Eastern tradition, the Divine Mother is the universal force, Shakti, who releases the light/action, energy/consciousness of this threefold flame of Spirit into the Matter cosmos through the precious hearts of her children.
