The Mantra of Purifying the Body is recited to cleanse the physical form of accumulated turbid energies (浊气) and to invoke the protection of the Four Celestial Animals — Azure Dragon (East), White Tiger (West), Vermilion Bird (South), and Black Warrior/Tortoise (North). These divine guardians form a protective formation around the practitioner, shielding both body and spirit from external interference. This mantra also harmonizes the energies of the Five Organs (五脏) and stabilizes the Hun (ethereal soul) and Po (corporeal soul). It transforms the practitioner's body into a sacred vessel fit for communion with the divine.
