notes, a 13th century description

I promised some of you I would locate the information on the relationship of the notes as laid out in the Sangeet Ratnakar of Sarangadev, a 14th century treatise on music:

“The sonant among them is considered to be the ruler, while the consonant, being in concert with it, is called the minister; the dissonant being antagonistic is likened by the sages to an enemy , the assonant, however, since it follows the king as well as the ministers, is like a servant.
