What stone is the coolest?

Because of the pure energy of obsidian, it belongs to energy absorption. In other words, it is generally recommended that Obsidian wear his right hand. Almost all the crystals are left-handed, except Obsidian, because according to the ancient Qi method in China, it is generally the principle of left entry and right exit. So the left hand is intake and the right hand is exhaust. Wearing obsidian in the right hand helps to absorb its negative energy, including unclean things.

Obsidian has a strong and pure energy, so it can be placed in a heavier place in Sha Qi, or even made into an obsidian Buddha statue, which is even better for avoiding evil spirits. But please note that obsidian itself can mainly absorb a lot of negative energy, but it will not be removed, so it must be purified within a certain period of time.
