Crystals have many different strengths and purposes. Some are useful when meditating or for enlightenment, whilst others can provide spiritual protection and help protect you from negative energies. The key is to choose the crystal that most closely aligns with the type of protection you require.
Acknowledging the presence of your aura is the first step towards opening your mind up towards a word of possibilities and a chance to use the energies that surround you in the best way you can. Those who are able to harness the energy of their aura will know that it isn’t as simple as a one-time thing. Your aura has to be protected constantly, reinforced through positive auric practice.
