I have always been mesmerized by poetic song lyrics. I relate to the learning that helps us know "less about before" as follows: the more we learn, the more we become aware of how little we know. In learning, we must shed our misconceptions of the past. This process is both humbling and exhilarating.
I am motivated to dig deep for clues on higher ground every time I am confronted with new insights that challenge my previous constructs. What helps me empty myself is to immerse myself in the process of learning, whether it be through observation, listening, reading, playing (e.g. a musical instrument), etc. I find that once I immerse myself, the process becomes the habit, and the insights that emerge spark a natural curiosity for this higher ground.
This question will generate a different answer from different people, but perhaps beauty is something that invites us to rise up beyond what we thought possible, because it speaks truth. I am a huge fan of music, and I tend to listen for beauty in music, which is to say that I like to feel that the artist is expressing what is truth to him/her. I have also read books that are beautiful. I try to bring this beauty into my work and life by remembering to be true to my values and ideals. This is often a challenge, since many forces pull us in directions that encourage us to be someone else, but when I can remember, it is empowering to feel this beauty.
