The title is a phonetic rendering of the spiritual classic, ‘Tao Te Ching’.
A more literal rendering would be, ‘How of the King’,
or even ‘Way of the King’.
All of which is quite widely known.
A little less known, perhaps, is that the text is an alchemical treatise.
Therefore, the king that it treats of in such fine detail is not necessarily an outer monarch of earthly empire.
The same can be said of many of the world’s spiritual teachings.
The compilers of these classic texts seem more than well acqainted with the maxim, ‘to transform the outer, change the inner.’
