Kybalion - The Hermetic Philosophy
The possession of Knowledge, unless accompanied by a manifestation and expression in Action, is like the hoarding of precious metals – a vain and foolish thing. Knowledge, like wealth, is intended for Use. The Law of Use is Universal, and he who violates it suffers by reason of his conflict with natural forces.
