What philosophy lectures means

In deep attention, the boundary between self and world softens - Daniel Goleman
It means that when you are truly, deeply focused, the mental wall you usually have up, the one that separates "you" from the "world out there", starts to dissolve.

Philosophy lectures Quote

Freedom arises when one sees thoughts as passing phenomena, not as the self - Daniel Goleman
The core message is that true psychological freedom comes from dis-identifying with your thoughts. You are not your thoughts; you are the awareness behind them.
