"Activities such as hearing, seeing, speaking, evacuating, etc., are actions of the senses meant for work." Really? Wait a second--aren't hearing and seeing what we do with our knowledge-gathering senses, not our working ones? But the quotation comes right from Bhagavad-gita As It Is, from the purport to 5.9. So how could it be wrong?
It's wrong because it's the first edition and a typist left something out.
See for yourself in the annotated scans for Chapter Five, now online at http://www.BBTedit.com/changes.
You'll see all the revisions done for the purports, along with annotations and with images from the manuscript typed by Srila Prabhupada himself.
Of special historical interest: For this chapter, Srila Prabhupada typed on the back of various printed pages, for which images are included.
Whether you're for "the changes," against them, or neutral, here's another opportunity to see what the changes actually are.
The changes for the Preface, the Introduction, and the previous chapters are already online. See them all at www.BBTedit.com/changes.
