Thanks again for this this interesting topic

I have another question : can we activate or open those gates by simply meditating and usual practices, as what we do to open chakras ?

I Imagine so. What is more likely to open it is the demand for the extra energy. When I was looking for more info on it I found on other sites people saying in reponse to similar questions that they can be activated through focusing and meditating on them much the like the chakras can.

cool! Thanks again (many, many ) for sharing this great info. This is really a brand nnew, yet interesting knowledge for me.
I cant resist to try this out, but up to now, I think I should hold back temporarily since my chakra level is still pretty low and unstable. I need to practice and iincrease more volume :D

I'm always exhausted easily when I mold brow chakra (I guess it's pretty much consumptive). So I guess I will keep focusing on my current practice before jumping ahead. Thanks again. This is really a piece of precious info Aegeus. I will try this out once I feel sufficient energy within me

I have observed people that focused on having lots of energy moving through there body but did not build up the body slowly to be able handle it and they essentially blew circuits. Which once done can be very hard to repair. Be sure to build up the body slowly to be able to handle the energy.

A while ago I was backpacking carrying half my body weight on my back and expending a lot more energy then anything close to what I had built up to. I still have a slight pain between my sternum and solar plexus. Aproximatley where the limit gate is in that diagram. So I guess I tapped into that gate to have the energy to keep up with the guy I was learning yoga from and am still recovering.
