Meditation is not a religious practice. It is important to be able to focus on only one thing at a time and meditation helps in doing that. It has spiritual relevance too but let’s not go into that now. I don’t meditate in traditional sense. For me, meditation means to focus on my body and my inner self without thinking of anything else. So, when I exercise all I concentrate on is my body rythm and breathing pattern and that’s meditation for me. Swimming is also an excellent option in which you have to concentrate on your body movements and breathing in order to swim well.
