Shankaracharya Maharaj wrote Vivek chudamani
Vivek – discrimination
Chudamani – crown jewel
What is discrimination or Vivek ? What is Atman or self. What is the non self ? Illusion of reality.
To know the difference is the crown jewel.
Or the crown jewel of discrimination is knowing self from non self
You know discrimination but have you experienced it?
Bhavin
