19.10

Under the third heading, [the practice of] both together, in the Śāstra, 'two meanings' refers to the aforementioned calming of all realms and contemplating the causes and conditions of arising and ceasing. 'Do not abandon each other': regarding these expedient means at the beginning of calmness and insight, although both may not yet manifest simultaneously when the practitioner cultivates them, while training in this, they must be practiced mutually supporting each other and cannot operate in isolation, casually abandoning one another. In the Commentary, 'having two essences' means that these two serve commonly as the essence for the ten perfections; it is like water: only when it is settled and then clear can it reflect images. Since the two gates open from the One Mind, how could they not possess both concentration and wisdom? The text above fully revealed this.
