If you want to ask Obsidian, please see the supplementary question.

Hmm ... I don't know what power obsidian has, but it is rumored that it can ward off evil spirits.

I want to answer two questions.

First of all, you may not like my first answer. This material was used in ancient times only because no more advanced materials were invented. Moreover, one of the purposes of obsidian used in Buddha statues is its "cat's eye" visual function, and its black color is very similar to the color of human eyes. At first glance, it seems to be alive, spiritual, psychological and religious. Living with your heart, caring for those who love you and learning to take care of yourself will make you luckier and happier.

The first answer is a more positive and healthy understanding.

In the second aspect, if you want to listen, obsidian is used for meditation, divination and wearing, meditation is used for energy gathering and conditioning, and divination is generally used for pendulum and tarot environment layout. Meditation has no substantive function, but actually implies itself. People who try to communicate with the pendulum are actually communicating with their own hearts (most people think so). As for tarot cards, many professionals do not recommend using crystal balls to assist divination. Personally, I think that everything is done by people.
