  Tamil is called "Theiva Mozhi" (divine language). The language itself teaches about human life and self realization. 1. Uyir ezuthu (Soul) 2. Mei ezuthu (body) They combine to make human body. There is one peculiar letter "Aayudha ezuthu". There is more meaning attached to it than it meets our eye. It is the weapon(aayudham) each human has to use to fight the evils - greed, envy, etc... The Aayudha ezuthu sysmbolises the three eyes of human. The two eyes on the face and one eye on the forehead forming a triangle. That is why tamilians wear kumkum on their forehead to show the importance of the place in the human body.
In meditation, we focus our eyes n thoughts on the third eye. The third eye is the eye for Immortality n enlightment. There are thousands of reasons why the first letter in tamil "Aa" is written that way and not otherwise. Saint Ramalinga adiggal explains these secrets in his book "Thiruarutppa". There are many saints in Tamil who had lived for more than 4000 years. And a many still living through many centuries. The lastest and most familiar one being Saint Ramalingam or Vallalar. He disappeared from human vision (didn't leave his body unlike many saints) in the 18th century. He is the only Saint who's miracle history appears in a gazette (British).
