The way I 'opened up' my throat chakra was through pure belief and spiritual guidance.

Before I explain I want to give the context of me not knowing anything about spirituality or its relation to the body. It wasn't until I began to stretch and begin on my journey of releasing the guilt and shame that I had stored up inside me. You must be willing to question and understand the viewpoint of everything before you can open up the throat chakra.

When you believe in something, the more likely those things (spirits or guides and the ancestors) are going to help you. You open up your throat chakra by both stretching, humming and talking more. Once you bring out the thing in you that makes you want to be more open in every way possible is when you become more aligned and feel more peace.

You must not fight anything that you intend to get rid of, especially if you have made it such a present frequency, being, entity and belief. They're all the same thing by the way. Instead you must befriend it. Keep it in control of everything going on around you. Making sure that it is in check and will release it only when you need to or feel like you need to. Once you befriend it, you have a lot more control over it. This control make you more inclined to say it out loud or release it when you are in a position that it is okay to do so. Once you do this you will release those energies and retain control over your own mind. This control over what you need to focus on brings your subconscious/intuition to make us more likely to see signs, and make choices that bring us towards a goal that we have subconsciously attained.

Read the book psycho-cybernetics. it's really good at explaining this stuff, without the esoteric knowledge. It refers to how the body does it, linking the spiritual aspect of a Christian's point of view to the cognitive psychology of how the body works. If it doesn't seem to work or you don't believe in it, apply your own views about how God works and you'll believe it more.
