In that sense: Akshira is a beat, or a 'count'
I think this definition is incorrect, as your disclaimer acknowledges.
The Sanskrit meaning of Akshara is "Letter".
In a musical context, Akshara implies a time-instant. I recall you used the term "Pulse" in another thread. So Akshara equates to a pulse. Multiple Aksharas make a beat. Conversely, a beat is sub-divided into aksharas.
If an "akshara" is an atom, a "beat" is a molecule. Got the idea?
In Tisra Nadai, you have 3 Aksharas in a beat, 4 Aksharas make a beat in Chaturashra Nadai, 5 in Khanda and so on.
The total time consumed by the aksharas of two different beats is constant.
The total time consumed by the aksharas of two different beats in different nadais is also constant.
Some implications follow from the above:
1. There are more aksharas in a beat of a higher nadai than a lower one.
2. An akshara in a lower nadai is of a longer duration than one in a higher nadai.
However, within a beat, all aksharas are of equal duration.
I also think Akshara and Akshara Kaala mean the same thing; the word "Kaala", which means "time", is perhaps to reinforce the idea that akshara is a time-related concept of Taala.
