I was first introduced to crystals by a friend and yes, I have seen them around shops. I recall that my dad has an amethyst geode at home. From my limited knowledge of crystals, I used to think of crystal usage in primarily Feng Shui functions. Feng Shui is a Chinese philosophical system of harmonizing everyone with the surrounding environment. Likewise, many New Age practitioners also use crystals for similar functions as Feng Shui practitioners.
There are two types of crystal collectors, the ones that keep them for their beauty and use them as decorative purposes. And there are the ones who believe that crystals have healing properties and use them in their various mediation or healing processes.
Crystals are thought to possess different levels of energy and have a vibration which can be measured, and according to the level of the vibration can be effective healers of individual chakras. The Sanskrit word Chakra literally Translate to wheel or disk. It is believed that the human body has seven centres of spiritual power,of which these are referred to as the chakra. I could go on more about this but let’s keep things simple and talk about my crystals first.
Crystal healing is an ancient art that dates back many years and I understand that there are studies claiming crystal healing to be pseudoscience. Some believe that it is just a placebo effect that people who had positive encounters with crystal healing. Personally, I would suggest going with your intuition. If you think that crystals are just a bunch of hogwash then it would remain what it is and never work for you. But if you have an open mind when it comes to crystals, then you might be surprised at what you would discover and experience.
