Mystery
Zhào (曌) - The characters of Moon and Sun over the character for 'Gold' (I have also been told 'Space').
A cursory translation is Bright/Shining, but there seems a depth to the arrangement that points both to Yin/Yang and Taiji.
The character was coined as an appellation by the only empress of China - Wu Zetian.
She ruled China at the same time as the scholar Fazang was writing.
Gil Fronsdal (a buddhist teacher/scholar) referenced a summation of Buddhism that Fazang was able to intuit/record:
Liberation Beckons From Within Everything.
