The Threefold Training for Contemporary Lay Life: Operationalizing Sīla, Samādhi, and Paññā for Self-Development in Thailand

บทคัดย่อ

Theravāda Buddhism remains the dominant religious tradition in Thailand and continues to shape lay ethics, family norms, and public moral discourse. Yet contemporary Thai lay life is increasingly characterized by accelerated work rhythms, digital distraction, rising interpersonal strain, and mental health challenges that are often addressed through fragmented “techniques” (e.g., meditation apps) detached from their ethical and wisdom foundations. This article proposes an applied model for self-development grounded in the canonical Theravāda framework of the threefold training (sikkhā): (1) sīla (ethical discipline), (2) samādhi (collectedness of mind), and (3) paññā (discernment/wisdom). Using documentary analysis of key Pāli sources—including the Satipaṭṭhāna discourse (MN 10/DN 22), the Noble Eightfold Path (SN 45), and lay teachings such as the Sigālovāda discourse (DN 31)—and integrating contemporary evidence on mindfulness-based and compassion-based interventions, this article develops a pragmatic “SST” (Sīla–Samādhi–Paññā in Daily Training) framework designed for householders. The model translates core doctrinal principles into operational practices: precept-based habit design and digital ethics for sīla; micro-practices of mindfulness, breath awareness, and walking meditation for samādhi; and structured reflection (yoniso manasikāra), causal mapping, and non-self reappraisal for paññā. Contemporary research indicates that mindfulness training can yield small-to-moderate benefits for cognition and psychological outcomes while Thai studies suggest additive protective effects when meditation is paired with precept adherence. The article further addresses ethical safeguards and potential adverse effects of contemplative practice, emphasizing informed consent and trauma-sensitive adaptation. The proposed framework aims to support evidence-informed, culturally resonant self-cultivation for Thai laypersons, and offers a program blueprint for temples, workplaces, and educational settings.
