I do not know what you are talking about. If you see the difference between regular life and Nibbana then your are really clueless about Buddha Dhamma.
Buddha Dhamma got nothing to do with focusing or calming the mind by the means of concentration. Once you understand Dhamma concepts mind transform permanently. It got nothing to do with numbing relaxation or calmness of the mind. We develop wisdom which finds also reflection in regular life so trying to divide that way to attain Nibbana is somewhat opposite to regular life is super wrong and you will only struggle which will lead to depression and giving up Dhamma because of own misunderstandings.
