1.19

Treatise: ...namely the true mind, up to: being constantly permanent and unchanging, completely endowed with pure dharmas, it is therefore called non-empty. (Commentary: This directly clarifies non-emptiness. "Namely the true mind": being empty and devoid of delusion is namely the true mind. This generally presents non-emptiness. The true mind is the greatness of essence; because it is unarisen, it is constantly [present]; because it does not die, it is permanent; because it is the self, it is unchanging—"self" has the meaning of sovereign mastery, just like the great ocean; because it is unchanging and thoughtless, it is completely endowed with pure dharmas. Although the nature-virtues are many, it mentions these four. That is the greatness of attributes of the true mind; being endowed with these essences and marks, it is called non-empty.)
