Hi Korpo:

Thanks for your reply.

Anyway, what I wanted to point out is that you can stimulate your chakras from the rear part, more that from the front. In my case it has worked very well, even better that if I do in the classical way.

When practising the microcosmic orbit, the chakras are touched when the energy flow pass through the front part. It doesn't work for me effectively. The other way, it does. That's all

A, and thanks for the comment about the dan tien. Some other description? Anyone?
