When we go to school or are with a learning environment such as a cushion, temple, retreat or sangha inspired forum, what do we learn?
A little more than the ostensible aims and subject matter. A little more than information.
It is the secondary capacity of the learning experience that is based on our processing and digesting that is often important.
So for example my teacher rarely talked about spirituality. It was something he embodied not something that was just information presentation.
To me 'beginners mind' is about this perpetual capacity to be a student, to learn, to expand awareness and potential. To share and celebrate rather than assume we have only to expand our little personal wheel. What? Another dig at the Hinayana? Tsk tsk, when will we ever learn not to be so serious ...
