I have just made an e-book consisting of most of my articles, letters, rebuttals, quotes, debates etc. from arsaprayoga.com.
Here it is:
Salt in the Caranamrita (04-10-2016-19-40)
You will always be able to find the latest version in the e-book section of arsaprayoga.com.
Spread the word.
Your servant, Ajit Krishna Dasa
