These principles can learned through the knowledge that music brings to our thoughts.
The ordering of life. To live in accordance with Nature and Spirit. Not to be swamped by the external trivialities of life. To avoid all that brings unrest and haste into life. To hurry over nothing, but also not to be indolent. To look on life as a means for working towards higher development and to behave accordingly.
To turn one’s gaze inwards from time to time, even if only for five minutes daily at the same time. In so doing one should sink down into oneself, carefully take counsel with oneself, test and form one’s principles of life, run through in thought one’s knowledge — or lack of it — weigh up one’s duties, think over the contents and true purpose of life, feel genuinely pained by one’s own errors and imperfections. In a word: labour to discover the essential, the enduring, and earnestly aim at goals in accord with it: for instance, virtues to be acquired. (Not to fall into the mistake of thinking that one has done something well, but to strive ever further towards the highest standards.)
