I always keep wondering whether what is published was what was written by Narayana Menon. If I remember correctly a brahmin was asked to "sanitise" it. I forget it. What came out was very bland. I think Narayana menon's daughter did not intend the commentary to be changed so much when she gave it to Amma. I may meet her - if she blesses - next week end. Then if she inspires I will ask.
