It's a difficult question. I also thought about the "Vril ladies." They were powerful mediums. Taoists and Yogis (men) They also wore their hair long. Like many shamans. On the other hand, Buddhist monks shaved their heads, and Catholic priests shaved their tonsure. It seems to me that long hair is important if spiritual practice is associated specifically with mediumistic perception, and not just with meditation or prayer. Shamans work with spirits. Many practices in Taoism date back to shamanism. Yogis, on the other hand, pull long hair into a bun on top of their heads, without leaving them loose. This may be some kind of intermediate option. Witches in traditional Russian witchcraft, when conducting rituals, had to let down their hair. They also worked with different entities, such as devils and demons. Sometimes with angels or saints. If the practice is associated only with inner efforts, meditation, as with Buddhists, extra "antennas" can be a hindrance. And what do you, my friends, think about this?
