When we collaborate research with the truth then we get more closer to that understanding behind the phenomenon we are studying. It could be either understand in terms of neuroscience, medicine, eating habits and everything let's take example - if two persons working at same place and one of them does meditation and exploring inner peace with spirituality on daily basis and know what is the truth of life he is comparatively more contentmed in life then a person who just sleep for physical rest, or do yoga or any other activities to make himself happy but he always wanted more and never satisfied with the life. To know what that truth is and and what that spirituality is just text (TRUTH).
