TRANSLATION
This has been said—
"Two grāmas named şadja and madhyama are well-known in the world."10
(Anu. <sup>33</sup>)
But why are there only two grāmas? It is being answered; here two grāmas
have been formulated on account of (musical) performance being rooted in
the usage of two svaras.11
"The svaras have attained the state of grāma through jātis and śrutis."12
(Anu. <sup>34</sup>)
"Through the jātis" means through śuddhās and vikṛtās (both types of jātis)
and through śrutis. Hence the svaras that are there in the śuddhā and vikṛtā
jātis, on account of disruption13 in their śrutis, (their) slight augmentation14 and
diminution and mixing up,15 (these) svaras have attained the state of grāma.
ṣaḍja - (grāma) is born of the śuddhā-(jātis) and madhyama (grāma) of the vikṛtās
and from the two (types of jātis) are born sankīrņās (jātis)16. From them (jātis) is
born rāga.17 On account of the change 18 of grāma the change in the jāti and
rāga occurs.
[ Thus ends the treatment of grāma ].
[ The treatment of Mürchanā ]
(Anu. <sup>35</sup>)
Now the murchanas that befit the occasion or context are being spoken of.
But what is the etymology of the word murchana and what is its lakşana
(definition)? It is being answered. The etymology of 'mūrchanā' is thus - (the
root) mūrch stands for moha (loss of consciousness, stupefaction, infatuation)
and samucchrāya 19 (increase, growth).
That through which raga 20 (colour, delightfulness) grows or increases, is
(90)
called mūrchanā.
