At Monday evening's group we read from one the Dalai Lama's books (Can't remember which one)...What we found interesting was he more or less said Nirvana is when one is free of all negative thoughts (not his exact words I should add)...and if one thinks about it (pun intended) ...it does make senses....And simplifies the definition somewhat...
Hmm the Twin Verses come to mind (well one take on them anyhow)
After all We are what we think.......but then again......we are not our thoughts
Some food for thought perhaps ...What do you think ???
