“Here the word Citta is used rather than Manas.
Citta is not used in Chapter Two,
except with regard to Pratyāhāra in verse 54.
Otherwise the term Manas is used,
as in when the mind is automatically
pulled out by external forces.
Therefore for many of us mind is Manas.

Unless there is a shift from Manas to Citta,
it is not possible to do Dhāraṇā.”
