What was the TS Purge?

In the following quotation from the Maria Monolgues (MM) regarding the second lit purge of 1991,(remember, there was an earlier one in the late 80s, so what they called the 2nd lit purge in 1995 was actually the 3rd) she refers to the TS Purge. Can anyone give me a description of what that entailed, or point me to where it is already written about? By the date on that MM it seems this occurred shortly before or around the time I left TF, but I don't recall it.


“One of the reasons I think that it's becoming increasingly urgent to get the Lit Purge material instructions out to the Family, but also to get the “Answers To Our Enemies” out to the Family, is because of this Tser Purge that we're having. I think this is definitely going to result in quite a few antagonistic parents who are not going to like being separated from their kids or leaving their children with their mate who stays in the Family. This may result in more problems like are happening at the moment in Australia. We can't help that, but we're going to have to be as ready as possible to “give an answer to every man that asketh it.” And also, to have our lit in a condition that will be useable for the Homes, yet able to undergo scrutiny by the System without causing us major problems.” (“Lit Purge and 'Answers To Our Enemies' Increasingly Urgent.” Maria Monologue #2, March 18, 1991, http://www.xfamily.org]
