Taoist sects refer to various religious organizations and movements that have emerged from the broader philosophical and spiritual traditions of Taoism. These sects often emphasize different practices, rituals, and beliefs, leading to a rich diversity within Taoist thought. Major sects, like the Complete Perfection and the Zhengyi (Orthodox Unity), illustrate how followers interpret the Tao, or 'the Way,' and seek harmony with the cosmos in unique ways.
