852 Hz is a frequency that is sometimes associated with spiritual enlightenment in some alternative healing practices and spiritual traditions.
According to some sources, 852 Hz is said to be the frequency of the third eye chakra, which is an energy center in the body located in the forehead that is associated with intuition, wisdom, and spiritual insight.
Some proponents of sound healing and meditation suggest that listening to music or tones played at 852 Hz can help to stimulate the third eye chakra, promote spiritual awakening, and enhance intuition and insight.
