While the names differ based on culture and language, they all refer to the same fundamental life force energy. Ki is the Japanese term (used in Reiki and Aikido), Chi (or Qi) is the Chinese term (used in Tai Chi and Qigong), and Prana is the Sanskrit term (used in Yoga and Ayurveda). Though the practices for cultivating them vary, the goal of balancing this internal energy remains the same.
