Simplicity

How do we define simplicity? Staying with whats bare need! And who will delineate greed from need? What is need for me can be termed as greed for some Mr.X/Y/Z. So how does one qualify for "simple living n high thinking"? By the way, why the heck should I try for "simple living and high thinking"? Whats so wrong about "high living and simple thinking"? Does simplicity brings happiness? I doubt it strongly. Lets take an example of the life style of a village farmer, whose life style we can brand as simple with a good agreement. But does that farmer know about the simplicity in his life? NO. Most of the cases, if the life is simple, then the man might not know that its simple. And if one knows that his life is simple; or in other words, he/she could afford a more luxorious life but still takes a less luxorious life..............then .......well i would say he/she is running behind some mirage. There is nothing great about simplicity. The notion it slef is relative and "one who knows that his life is simple loses the merit of it"!!
