I am sure you heard the term, spiritual healer, shaman, astrologer, priest, magician, witch, and psychic. Every one of these works using the spiritual realm to obtain information, alter reality and perform healing.
Spiritual healers utilize their own energy, angels, ancestors, crystals, amulets, and ancient rituals to perform healing work on their clients. It is important to choose the right healer and ensure that they are reputable. Spiritual healers that use their own vibrational energy when performing healing will leave a small portion of their energy in your aura, this is common with everything including relationships and friendships. You want to work with someone that is not only trustworthy but also happy and full of life, so that the transfer of energy is beneficial to you.
Spiritual healers that spend countless hours in meditation, will have a higher vibrational energy, like the angels. Therefore, they can shift energies with thoughts, and many gifted healers will also be able to see and move energy around with their eyes. When you hear about a great healer, usually the experience is shared by many because their vibrational energy is very high and radiates to others.
