This paper offers a rigorous examination of the concept of prosochē—the attentive mindfulness or vigilant focus on oneself—within Hellenistic Stoicism and its later transformations in Late Antiquity, and compares it to the modern psychological notion of the “flow state.” We analyze prosochē as a Stoic spiritual exercise (askēsis) essential to ethical development and life in accordance with cosmic reason (logos). Drawing on Pierre Hadot’s work and other scholarship, we detail how Stoic thinkers (especially Epictetus and Marcus Aurelius) conceived prosochē as continuous self-awareness and moral vigilance, and how this practice was adapted by Neoplatonist philosophers and early Christian ascetics. We then develop a comparative analysis between prosochē and Mihály Csíkszentmihályi’s concept of flow from contemporary psychology. Notable similarities include focused immersion, a harmonious affective state, and a sense of mastery or control during the experience. Key differences are also highlighted: prosochē is grounded in a teleological and moral framework oriented by cosmic nature and virtue, whereas flow is a content-neutral psychological state defined by optimal experience and lacking inherent ethical orientation. In sum, the paper situates prosochē as both an ancient practice of attentive presence and a precursor, with crucial differences, to modern ideas about absorbed states of consciousness. Footnotes provide references to primary sources (Epictetus, Marcus Aurelius, Plotinus) and modern analyses (Hadot, Csíkszentmihályi, cognitive science research), and the conclusion reflects on the enduring relevance of prosochē for philosophy and psychology.
