How to evaluate your Chakras?

[Plenum]

How do you tell if you have a blockage in a specific Chakra?

The best way is to observe consciousness.  This is a feedback mechanism that everyone has access to.  Depending on experience and training, one may then be able to pinpoint the nature of the blockage/non-acceptance to a specific area in the body.

I'm assuming it's not a physical sensation, or is it?

It can be, depending on the severity of the blockage.  

I've read the theoretical part, regarding what each Chakra represents, but I'm struggling with the practical part of determining which Chakras are blocked or distorted.

I think the best way to view the energy centres is that they are an interface between consciousness and expressed matter.  That is, it is how the mind 'manifests' the body, and it's concurrent conditions.  Emotions and Feelings are things guaranteed to 'move' the energy centres one way or another; in the same way they throw ripples in one's linear thinking.  Once feelings and emotions are triggered by 'experience', then one's thought process shifts into a different gear.  There is more 'potential' available once feelings and emotions are discerned.  

Do you have any tricks or techniques that you use? Any insight would be greatly appreciated.

My feeling is that putting the energy centres on a psychological footing, rather than a physical/energetic one yields the greatest amount of self-empowerment.  Not everyone is able to'feel' their energy centres, as physical sensation, but everyone can observe the motions of their mind.  It wasn't until I came across Ra's explanation of the energy centres that I was able to find a place for the 'chakras' in my life.  Because all the other explanations I had come across didn't provide this holistic, mental/emotional/spiritual linkage and set it in a developmental framework.  They were just abstract funnels of light.

if you haven't yet read it, Carla wrote a great introductory text called: Living the Law of One 101, which will give this psychological foundation for the energy centres.
