If you land on any svara occurring only in arohana you are permitted to ascend to any note in ascent occurring in either aro or avaro. You are always permitted to descend to any note occurring in the avaro.
On the other hand if you are on a note occurring only in the avaro then you are permitted to descend ( not ascend to any note in aro or avaro!
Is this not discrimination?
If you land on any svara occurring only in arohana you are permitted to ascend to any note in ascent occurring in either aro or avaro.
Yes. But in practice, the neighbouring note in arohana would be most common.
You are always permitted to descend to any note occurring in the avaro.
FROM the same above swara
occuring only in arohana? No - you cannot descend period.
On the other hand if you are on a note occurring only in the avaro then you are permitted to descend not ascend to any note in aro or avaro!
Yes. This is just similar to a note occuring only in arohana - the only difference is here you descend and there you ascend. Also, similar to above, from such a swara you cannot ascend period.
A simpler way to look at this (consider non-vakra scales only for now).
From any swara, you can ascend if it is in the arohana.
From any swara, you can descend if it is in the avarohana.
In other words, focus on the transition *from* the swara,
NOT the transition *to* the swara.
Consider s-g-r-s for in sAvEri. There are three transitions and you are
1. ascending FROM sa
2. descending FROM ga.
3. desdending FROM ri.
So you ask
1. Ascending from sa. Is sa in arohana
?
2. Descending from ga. Is ga in avarohana?
3. Descending from ri. Is ri in avarohana?
The answer is true for all three and so allowed.
Consider the same s-g-r-s for our raga s-r-m-n-S/S-d-p-g-s.
1. Ascending from sa: Is sa in arohana? Of course yes
2. Descending from ga: Is ga in avarohana? Yes.
3. Desending from ri. Is ri in avarohana? NO.
So s-g-r-s is disallowed for our raga.
But s-g-s would be allowed although probably "not common" (as swara skipping as is done in s-g while allowed need to be used judiciously in cm).
Consider these:
Is d-n-d allowed or not in kambhOji/bilahari? Why?
Is d-n-R-s allowed or not in kAmbhOji/bilahari? Why?
Is S-n-d-n allowed or not in bahudAri (s-g-m-d-n-S/S-n-p-m-g-s)? Why?
Is n-d-p-d-n allowed or not in bahudAri? Why?
If you apply the above procedure, and you will arrive at the right answer for each case.
