How and why did you choose to ask the questions you asked for the interviews?
When I arrived in Mysore in the early '90s Guruji used to give regular theory classes, but his ability to communicate was often thwarted by language problems.
Guruji spoke a little English but he had a strong accent which was often hard for English speakers to understand and mostly impossible to understand for non-native English speakers when he started to talk about philosophy.
In the first few years I was there, there were 15-20 students at his theory classes. We were French, German, English, American, Dutch, Swiss… a jumble of languages with varying limitations on the grasp of Guruji's broken English and Sanskrit. So his efforts were often mired in frustration. I felt for him (and for myself - I was also frustrated we were unable to learn more from him in this forum).
