I will explain the main energy portals for this physical dimension. These are the portals that I (currently) work with during crystal healing. Although I am quickly learning about many other dimensial portals. But that is for another time.
The person lays down. On top of their head is located the 7th, or "crown" chakra. This chakra relates to their spiritual connection and how much they trust that everything will work out. If the energy is low her, then I put various crystals on the ground above the head (0-1 in away from the top of the head).
6th chakra: this chakra is located in between the eyes. If it is low, a person is having difficulty knowing their own feelings from day to day on various matters, or is having trouble reading the feelings of others. If I am to lay crystals for a low energy 6th chakra, I will put crystals between the eyes, or even on each of the eyelids.
5th Chakra: this chakra is located on the throat. It represents a person's ability to speak up for themself, express their opinions, and be heard. It also represents creativity and self-expression. If this chakra energy is low, I place crystals on the throat.
4th chakra: located in the middle of the chest. This chakra reflects self love. It is mainly green. There is another chakra located in front of it that is pink. But that is another chakra.
3rd chakra: naval chakra; it is located between the abdomen and chest. It's primary color is yellow. Yellow represents actions, happiness, health. This chakra is about vitality and sense of self.
2nd chakra: abdomen. This chakra is about relationships with friends and love. If a love relationship is off or hard to develop, then this chakra will be weaker. The color is mainly orange.
Root chakra is very important. It represents all physical illness and pain. An illness in the abdomen is still a first chakra issue. The lower the energy of first chakra, the more a person will struggle with health, sense of place, and groundedness. This chakra is very very important. You can use red or black stones and roll them up under the tailbone.
