really every one is doing meditation. if you are a shop keeper so you are dealing with the customer in concentrate way is like meditation. if you are driving  a car ,driving safely is apart of concentration like meditation. meditation/concentration/ action/ thinking may be positive or negative. thief also his his work in concentration way, if he looses  becomes my opinion our all activities must be dedicated, in pleasure mood and full of joy. please do no harm to any one and own self also. because match stick first burns then makes fire or burns to others.
