Answer:
The correct answer is 5. The religion in which followers complete purification rituals in a sacred waterfall in order to commune with nature is Shintoism.
Explanation:
This ritual, called Misogi, is a cleaning ritual in the Shinto religion, which takes place twice a year. The faithful clean themselves before worship in a waterfall or in running, mostly cold water, before sunrise.
Special clothing is worn for the ritual, for women this is the white kimono and a headband, for men a loincloth and a headband.In addition to body purification, it can be used to be possessed by a spirit, invoking it during ablution.
Purity is considered an indispensable feature for contact with the divine and for this reason purification ceremonies play a central role in the Shinto liturgy. To this end, the faithful are also required to practice other sacred rituals, including meditation, fasting and breathing exercises.
