changes in perception which may lead to the unblocking.

this is true. All blockages are based on belief patterns that are inconsonant with unity.

ie change your mind (belief patterns), and clear you chakras.

you can do this temporary by considering high-minded thoughts, working with positive material, but then your 'baseline' will return to default if the deeper 'belief patterns' have not been altered fundamentally.

deep change = change of deep beliefs about self (usually beliefs instilled or accepted as a child, ie religious brainwashing as you have related)

I had to really dig down deep to remove the beliefs I accepted about myself due to others 'rejecting' me for my race. I've explained that I grew up as one of the first asians in a fairly conservative, middle class white suburb. That belief that 'asian' was defective, weak, different, 'smelly' etc I took on board as me being 'damaged' or 'not good enough' to survive. basically a whole complex of lower triad blockages based on negative views of myself and who I was. Of course, these 'beliefs' are totally untrue and nonfounded, and so clearing them has lead to the more 'truthful' free flow of energy in those lower chakras.

but the inner work and inquiry had to be done. But it can be done :d
