The following verse, even though not directly related to the capital letters subject or changes to SP's books, has been helpful for me to keep focus on how to approach the conversations on the two current threads.
As I only have the current BBT versions of Prabhupada's books, and to be honest find them very nice, I will reflect on this verse....in case any of Prabhupada's words are subtly changed due to editing in the latest versions.
SB 1.5.11 from Sri Sri Prapanna-jivanamritam 1.6 by HH BR Sridhar Swami.
"Even if every stanza is imperfectly composed, that is, unlucidly expressed, the sins of the people are totally vanquished by those expressions or books in which the holy names of the Infinite Supreme Lord are described - since the pure devotees hear those holy names (from a qualified preacher), they solitarily sing those holy names (even in the absence of others), and they chant the unending glories of those holy names (in the presence of a deserving listener)."
Maybe if I can hold this verse in my heart and Srila Prabhupada's words from the previous link also; just maybe in some thousand or so years from now when I am still roaming this planet I maybe able to extract the essence of love of Krsna from whatever remants of scripture I have acces to at that time.
