Don't only practice your art, but force your way into its secrets; art deserves that, for it and knowledge can raise man to the Divine.

This quote is encouraging people to learn and practice their craft, but it also suggests that they should go beyond that and attempt to gain a deeper understanding of their skill, and how it can help them reach a higher state of consciousness, or a “Divine” state. It implies that art and knowledge, when combined, are capable of bringing a person closer to a sense of spiritual enlightenment.
