I learned from Mantak Chia (not directly, through some of his masters and books and tapes)

We can align our own chakra's - unblocking them is actually part of our life lesson, because we hold issues within the chakras. Often even when we think that we have done the work we are still in need of a tune up. I would say that it is an internal job, in the sense that it is linked to self love. Working through the chakras helps us to remove blockages that we are holding. Yet we would then need to ensure that they are aligned, otherwise we may pick up issues, toxic feelings again. This work can take a lifetime to be honest, because our chakra's are linked to our feelings and these change daily. We can recognise where our thoughts are in regard to each chakra and the area that it governs - eg: root chakra safety and security (also includes basic needs food, water etc) - to totally clear and heal this chakra we would need to feel safe and secure most of the time and most of us struggle with this in the culture that we live in.

I agree with FairyCrystal.
Mental and emotional issues are reflected to the energy body as blocks.
Energy work can indeed clear the blocks,but the result will be temporary.

The blocks will apear again soon.

There is an old meditation cd by Stephen Halpren called Chakra Suit that is still available today. Each song is in a key that corresponds to one of the chakras. You can listen to that while you are laying down relaxed and visualize that chakra taking in energy, spinning, and becoming infused with the corresponding color. When I do this meditation, I generally start at the bottom of my feet and visualize energy flowing into the bottom of my feet and moving up my body and through each of the 7 main chakras and up my spine and out the top of my head to flow down my body back through my feet again in a continuous cycle.

Likening the chakra zones as correspondent to an energy spectrum, say root as red, sacral orange and so on going up to violet in crown, the flow of energy is impeded by fears and desires or beliefs correspondent to each energy vortex or chakra. For example, root, where kundalini is dormant, choosing between conscience and ego (aspects serving mind-body). A question is asked … our answer in lived reality, thought, word and deed, determines the shift.

Likewise, we can plot out free will choices for each energy zone as also layers in between. That which is egocentric lowers, that which is love oriented, raises. As such, it’s pointless, in my view to conjure a thought related to employing force to activate or cleanse any chakra … we don’t even know what it is until we feel it … feeling, an effect, consciousness shift, the cause.

So … affinity. What’s our reflex instinct? What are our feral urges? Our fears? How aware are we, moment to moment, in stillness? Perhaps these are the musings which would be helpful. As we choose to be, we are and so become, if we prioritise God search.
