The omission of a samvadi of the amsa is not accepted in jāti transformations
"Şādja-madhyamā does not become ṣāḍava on niṣāda being amsaand also on
gandhara (being amsa), because the omission of a samvadi of the amsa is not
accepted."

When pūrvaraiga is performed the organisers of song should use the śuddhā (jātis) in āsārita,<sup>47</sup> pāņikā <sup>48</sup> and the like and after that the formation
(alteration) of anisas of jātis (should be taken up).
(249)
Along with the order of \bar{a}s\bar{a}ritas^{49} and because of that of the angah\bar{a}ras^{50}
the formation or variation of amsas in their svaras i.e. in svaras of jatis should
be done in the text of vardhamāna<sup>51</sup>

[8. The ṣāḍava and auḍava formation of jātis]
The sixty-three amsas that have thus been spoken of, out of them each one
is accorded the position of ainsa (at a given time) (and accordingly) the
ṣāḍava and auḍava formation that is obtained (on account of rule or
prescription) is sometimes given up.

[ Anu. 134 ]
The sixty-three amsas that have been spoken of, out of them each one has
to be arranged as anisa (in a given melodic set-up). (In specific situations
created by the arrangement of different anisas) sometimes the formation of
ṣāḍavita and auḍuvita that is obtained in the context of a given jāti, is given
up. He (the author) clarifies this itself.
Şādja-madhyamā does not become ṣāḍava on niṣāda being amsaand also on
gandhara (being amsa), because ^{52} the omission of a samvadi of the amsa is not
accepted.

[ Anu. <sup>135</sup> ]
This means that on niṣāda being the aṁśa, the jāti ṣadjamadhyā does not
become ṣāḍava. Why? In ṣaḍja-grāma, in the prescription about ṣāḍava the
omission of gandhara is not there. On gandhara being aṁśa, it should be
known to be non-ṣāḍava by omission of niṣāda because of the negation of the
omission of the sanivādī of the aniśa.
Kaiśikī, raktagāndhārī (and) gāndhāri, (these three jātis do not become
ṣāḍava) when pañcama is aṁśa, (by the omission of ṛṣabha on account of the
negation of the omission of the samvādī of the aṁśa). Similarly, ṣāḍjī does
not become ṣāḍava through (the omission of niṣāda) on gāndhāra being the
aṁśa and şadjodicyavā should be known not to be şādava (through the
omission of ṛṣabha ) on dhaivata being the aṁśa.
