Is it true that there are seven passes in Taoism?

Not only in Taoism, but also in Tibetan Buddhism. These are the gates that are necessary to focus on when practicing meditation. The bottom chakra (perineum), the navel chakra (dantian), the abdominal chakra (supra-dan), the throat chakra (nodus), the eye chakra (yintang) the top chakra (Baikoumen), and the celestial chakra (Wuji Men). There is no such thing in Southern Buddhism or Chinese Buddhism.
