The Roles of Reasoned Attention (Yonisomanasikara) in Theravada Buddhism: An Analytical Study

Abstract

This paper provides an analytical study of the roles of reasoned attention (yonisomanasikāra) in Theravāda Buddhism, emphasizing its significance as a foundational practice for cultivating wisdom and mental clarity. Reasoned attention, often described as systematic or wise consideration, is a mental faculty that enables practitioners to discern the true nature of phenomena by reflecting on them with proper understanding. This study explores the various ways in which yonisomanasikāra is applied within the Theravāda tradition, particularly in the context of ethical conduct (sīla), mental concentration (samādhi), and wisdom (paññā). Drawing from key suttas and the Abhidhamma, the paper examines how yonisomanasikāra serves as a crucial antidote to unwholesome mental states, such as ignorance (avijjā) and delusion (moha), and supports the development of right view (sammā-diṭṭhi). By fostering a deep, analytical approach to experience, reasoned attention aids in the penetration of the three marks of existence—impermanence (anicca), suffering (dukkha), and non-self (anattā), and thus plays a pivotal role in the path to enlightenment. This study underscores the importance of yonisomanasikāra in daily practice and its relevance in addressing contemporary challenges in mindfulness and cognitive development.
