What Are The Merits Of Meditation?

Meditation is quite a useful technique having a deeper proclivity towards nurture than nature.  It is a technique that is meant to capture attention and refocus it in a way that generates and accentuates a state of consciousness that is different from before.  A type of meditation known as transcendental meditation, a person is made to iterate a mantra, over and over again, concentrating his / her full concentration on it until he / she reaches a state where no outside stimulus works on his / her senses and the state of consciousness of the person reaches a whole different phase.  

This refocusing rationale of meditation is a universal phenomenon nevertheless its mode of application differs from culture to culture, sometimes even from person to person.  Because of this variation, different cultures have developed their unique methods of changing the states of consciousness.  Although the need for meditation and the rationale behind its application still remains a universal need.
