The 2 serpents of Kundalini energy in our bodies represent yin and yang. When they meet at the Third eye it creates awakening or enlightenment. I want you to visualize these 2 serpents as yin and yang, black and white swirling fast and rising up to the third eye creating lightning and i want you to send this lightning to flow down your arm and out. If you can't project it simply ground it: get inn a low stance, legs apart and exhale while letting electricity down to ground. Works best for Indigos since they are awakened already. Practise each day and importantly be neutral! Be calm and free from thoughts.
