People starting to practice concentration exercises, sometimes experience certain peculiar sensations, and wonder about their cause, and whether they should keep exercising.
Several days ago someone asked me about these sensations, and I decided to share with you this information, as I believe many have probably experienced these or similar sensations.
Here is the question:
“I started concentration exercises some time ago, and I know I have improved, but the question is regarding the after effects of concentration. After a 15 minutes session I feel a kind of heavy numb feeling in my head and face at the front. It is not bad (not painful), but it is just there and it goes away later. Sometimes I feel like there is nothing in my head. I feel really light and have a lot of clarity. I am more concerned of the first feeling, is this common or is it just me?”
These, and other similar experiences, such as headaches or physical tension are not uncommon, and there is nothing to be concerned about. Years ago, when I first started to work on improving my concentration, I had the same exact sensations and feelings.
There are several factors that cause these sensations:
1) When beginning to practice concentration exercises, the brain is not accustomed yet to focus intently on one thought or object, and this puts some strain on it. The mind and the nerves in the brain are not able to stay quite, and it takes time to discipline them and teach them new habits.
