The neck chakra is also the key to our base in life, past lives, and our soul's pattern. If you want to dissolve some past life matters, use this chakra with the one that activated the pattern to get it solved.
The most vibrant color in this chakra is the one that responds to the chakra connected with the pattern.
Magenta, if you want to seek experiences and development and memories from past lives. It is the color for growth and more profound insights about yourself and your spiritual way in this life.
This chakra has qualities, memories, and experiences with all your identity, life after life, event after event, and all the energy you have behind you. And if you think about it, when you're tired, doesn't it happen that you put your hand on your neck, an unconscious reflex of you trying to stop the energy from leaking.
The neck chakra is also a passage to your past, in this life, and from the previous life. Its pours backdoor into the soul and the chakra where we put all the things we can't handle, worries, debt, and angst. Women tend to get a bump on their necks; maybe it's the energy built up here.
Since the neck is where all the responsibility is represented on the body, and women often have problems saying no and taking responsibility for themselves, this chakra tells about it.
The neck is to hold the head up, and if that part of the body doesn't work, anything else will either. In Reiki (Japanese healing art), the neck chakra is used to close, to look at the energy wheel so nothing can get through, not out or in.
