Book excerpt: Mind and Its World I begins a detailed analysis of the subjective side of experience. It examines mind and how it perceives its world in valid and invalid ways based on the Classifications of Mind, which provides divisions and definitions of the types of mind identified in the epistemological tradition of Dignaga and Dharmakirti. The key point is the discernment of the aspects of mind that validly perceive things the way they are, which are distinguished from those aspects of mind that are mistaken and tainted by fundamental delusion, and thus keep one bound in samsara. It also introduces the two Hinayana philosophical systems, the Vaibhashika and Sautrantika schools, covering the two truths and the process of perception. Selected readings, analytical meditations, study questions, review summaries are included in the sourcebook.
