Golden Light of the Heart

The golden light that fills the inner essence is a characteristic sign that the heart is being armed. Just as the outer reaches of the aura turn from purple to ruby, the silvery Lotus of the heart flashes with a burst of red and gold when the spirit dons the ultimate armor. That is how an inner condition is attained that allows participation in the fiercest battles without harm or risk of the subtle body being severely wounded. The results of this armoring of the heart were already evident when the warrior stood up to the dark forces and, in spite of their overwhelming numbers, made them tremble. She left them with their threats, and the empty threat of an enemy is in itself a victory. Naturally, the pure golden light is not easily attained; it requires a lengthy achievement.
