That caturanga is pronounced <chaturanga>, ¿qué no?

Yes, sorry about that. I'm used to the standard Devanagri transcription system. There's both an unaspirated {c} ~ /tS/ and an aspirated {ch} ~ /tS^h/ alveolar fricative. I've never been able to hear the difference, but then IANP (I ain't no pandit).
