[57] By way of one, the aggregate of perception (saññākkhandha) is associated with contact (phassa). By way of two, the aggregate of perception: there is that with conflict (saraṇa); there is that without conflict (araṇa). By way of three, the aggregate of perception: there is that associated with pleasant feeling (vedanā); there is that associated with painful feeling; there is that associated with neither-painful-nor-pleasant feeling; … there is that having an internal object (ajjhattārammaṇa); there is that having an external object (bahiddhārammaṇa); there is that having an internal-and-external object (ajjhattabahiddhārammaṇa); … Thus, by way of ten, the aggregate of perception.
