What is the mean of 'samma ditti' in Ariya-Ashtanga Marga? Everybody, who is learning Buddhism know that 'Samma Dhitti' is the 1st of 'Ariya-Ashtanga Marga'. It's surface meaning is 'Right vision'. But what is the exact meaning of it? 

It is a one procedure of 'Ariya-Ashtanga Marga' to achieve 'Nirvana'. I want to know the deep meaning of it. How to achieve right vision or Samma Dhitti? Is it a procedure of our thoughts? 

If we go to the 'Samma aajeewa','Samma kammantha','Samma wacha''Samma wayama', we can describe them as procedures or habits. But I get a feeling that 'Samma Dhitti' is more than that.
If a virtuous person were to constantly reflect and expand upon even one strand mentioned in the Samma Ditti sutta referred by Suminda above, it will be for his long term benefit. 

For example one can take the section on the four types of Food and constantly reflect on that reality and confirm that view. 

Mr. Piya Tan has written an in depth commentary of the Samma Ditti sutta here.
