This class introduces the foundational concept of prakṛti—an individual’s unique constitutional nature—as an important lens for understanding health, behaviour, and therapeutic approaches in Ayurveda. We will review the essential theories behind prakṛti, including the guṇāḥ (qualities), bhūtāni (elements), and doṣāḥ (humors), and examine the role of prakṛti in both diagnosis and prevention. Participants will explore how constitution informs general considerations for diet and lifestyle. Through demonstrations, self-assessment, and practical tools for evaluation, students will learn to recognize constitutional patterns and apply this understanding in both personal and clinical contexts.
