9.192

肇曰：樂說辯，四辯之一也。上云念定持辯，此云念持慧辯，定慧互有其用，迭在四門者也。

[Seng]zhao says: The eloquence of pleasant explanation is one of the four types of eloquence. Above it spoke of 'mindfulness, concentration, retention, eloquence'; here it speaks of 'mindfulness, retention, wisdom, eloquence'. Concentration and wisdom each have their functions, alternating among the four gates.
