We explore three increasingly subtle aspects of wisdom and the speech practices related to each of them: (1) the wisdom to know what is wholesome and unwholesome, particularly in an ethical context; (2) the wisdom to know suffering and the roots of suffering, and freedom and its roots; (3) the wisdom to know the nature of more direct experience and the nature of concepts. In all types of wisdom, the basis is the close study of experience, leading to insight and clear seeing.
