Dear Professor Wujastyk,

Thank you very much for drawing my attention to these publications.

I don't quite agree with Tuske on many points, and I can tell a lot about how these "philosophical" traditions welcome and promote the cultivation of positive feelings and emotions, such as infinite selfless love, compassion, contentedness, tranquil joy etc (contra his thesis that they seek to eradicate "emotions"), but, regardless of that, the very last sentence of his paper strikes me the most, as my question was about the very language of the tradition:

"However, any comparison must be sensitive to the difficulties in translating the concepts involved".  

This is exactly what I am talking about: how we are supposed to understand the texts, if we can not even translate them adequately, find the right words... 

Kind regards,

Gleb Sharygin
