Concentrating on Breathing I have been experiencing energy flow on my head,especially at the tempels,  even after meditation. I have only started on Breathing concentration. What is it? I have stopped meditation for fear of something wrong might have happened. 
Thank you.
According to my experience in meditation, first time it was happened to me. Do not fear to do the mediation. 

These are the steps for Anapana-sathi meditation. 

1.Concentrate your mind into breathing process.

2.In that time,try to think about only breathing patterns.

After you do it more times you feel relax in your mind.
It gives you to easily concentrate for your work.
