Masih al-quloob Mawlana Masihullah Khan (Allah have mercy on him) said,

Stay among people, but remain aloof.

Your body should be among creation, but your heart with the Creator. This will ensure that negligence does not overtake you. Beware of such negligence lest you conform with people in a way which entails opposition to Allah and His displeasure.
