The first time I did the technique with the 8th through 12th chakras I became nauseous and had a slight headache. I felt like motion sickness to me. Has anyone experience this? Do you think it has something to do with all the 'spinning'?
Thanks,

It has to do with not letting the energy through you.

It also has to do with feeling that much energy all at once.

It has to do with being a bit to mental or using to much logical thought in the process.

There are more possibilities as well but those are some of the common ones.
