>>While such naughty modern Vipassana teachers may be out there I have never read any or practiced with any modern Vipassana teachers
who have not put bare attention into its much broader Dhamma context.<<
For those interested, here is a guided vipassana meditation by Joseph Goldstein:http://www.dharma.org/ims/mr_audio.php#
. This form seems to that used by most Vipassana teachers, at least those connected with IMS. Nowhere is bare intention mentioned. But, I think bare intention as not adding imagination to whatever enters a sense door (seeing in the seeing, etc.) is implied.
