Physical phenomena and sensations are no accurate measurement for occult phenomena.
Therefore, one cannot measure the activation of the chakras based on physical senses, nor should one associate physical symptoms with chakra activation, since there are many other causes of a physiological nature that might be the issue. This is why it is best to monitor your symptoms and to approach the proper specialist if the problem continues.
As for the Distance Learning Course, I am not responsible for that. One of our other administrators can help you with that.
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
