I feel it would be valuable to remind ourselves of the way in which we should engage in discussions about the posts that are made to the site. For this, I have located several messages to the Advaitin List, dating back to 1994(!) from Ram Chandran and Dr. Sadanananda.

First of all, the dctionary definitions:
saMvAda – speaking together, conversation, colloquy with; assent, concurrence, agreement with

vAda – speech, proposition, discourse, argument, discussion, explanation or exposition (of scriptures etc.); dispute with the aim of reaching the right conclusion, irrespective of who ‘wins’. 

jalpa – talk, speech, discourse; disputation with ‘overbearing and disputed rejoinder’; arguing for the sake of winning, irrespective of who is right. 

vitaNDa – cavil, fallacious controversy, perverse or frivolous argument, criticism; argument purely for the sake of winning the point.  

kutarka – fallacious argument, sophistry
