how to mentally clean your aura

There are 7 layers in our aura. When we use meditation
and try to 'clean' it, we have to clean every layer. Many new age mystics
just tell you imagine and visualise a white light coming down and engulfing
your whole aura, this sometimes does't work well. I usually clean every
layer as I go along. Start by doing some kind of relaxation procedure
like counting 1 to 10 or say to yourself, upstairs, downstairs, over and
over again until you feel bored and sleepy,or you can get some relaxation
music to help you get to alpha or theta brain states. Once you done
that, mentally say to yourself " I am at level 1' and move your awareness
from head to toe or vice versa, the idea is to scan your level 1 for blockages,
once you sense 'something there', move your awareness to it, it should
'melt' or disperse. If it is still there, try breathing it colors, you
have to experiment with the color that will remove the block, repeat the
same procedure with all other level, eg. I am level 2, I am in Level 3,
When you say this, you are telling your mind to adjust to the next level
using intent, Intent is the force that changes the level. Some times if
you are at level 1, and you sense something 1 feel in front of you and
you cannot get it off, and you try the usual color breathing method, This
could be due to the fact that this blockage is actually at some other
level eg. Level 3 and you can usualy remove the block if you move your
awareness to level 3. Sometimes when you move your awareness into the
blockages, you get 'impression' like a past event or sometimes it plays
like a movie in your mind's eye, this is usually the reason for the block.
