Luxury is not a new word for man. From history we come to know that people of noble families used to live with all aristocratic amenities to show their prestige.
Modes and trends of luxury may differ from time to time but its actual nature as well as purpose of showing status doesn’t change ever. The level of prestige of a high-class family is completely different from a middle and lower one that shows its’ real nature of living.
If you want to know about the habit, living style and mental status of a person then you can know about them by his means or ways of daily life. A higher class family may use costly apparels, jewelry, expensive accommodation place and other things that keeps value at a particular time period of a society. But a poor family can also have such things according to its level.
Some eminent scholars don’t take notice of the life style only for luxury purpose. Instead they try to know about the mentality and living habits of a person also. So all these things keep matter to get the actual nature of luxury in human life.
