This discourse is not only outstanding for the great variety of themes it treats, but also for the fact that its chief protagonist is a bhikṣuṇī.
Bhikṣuṇīs are considerably less prominent in early Buddhist texts than their male counterparts, be this as audience to discourses spoken by the Buddha or as speakers on their own. The reason for this is not far to seek. Several Vinaya rules prohibit the travelling together of monks and nuns, in order to avoid suspicions that they might be having amorous relations.
Even the Buddha could apparently become the object of similar suspicions.
Such instances reflect ancient Indian concerns about relations between celibates and the other sex. These concerns make it only natural for the Buddha to refrain from setting out wandering in the company of nuns.
