Dk 5Nāmarūpapratyayaṁ ṣaḍāyatanam

Commentary on the Sūtra Nāmarūpapratyayaṁ Ṣaḍāyatanam (Dk 5)

Context

This sūtra belongs to the Abhidhamma Piṭaka within the Pāli Canon, a collection of deeply analytical discourses on the Dhamma. The Abhidhamma Piṭaka is regarded as a detailed exposition and analysis of the Buddha's teachings found in the Sutta Piṭaka, compiled by disciples and Dharma scholars of subsequent generations.

The title Nāmarūpapratyayaṁ Ṣaḍāyatanam may be rendered as "The Six Sense Bases as Conditioned by Nāmarūpa." This is a central topic of Theravāda Buddhism, directly related to the Four Noble Truths and the Middle Way as taught by the Buddha.

Principal Content

This sūtra explores the causal relationship between nāmarūpa (name-and-form) and the six āyatanas (ṣaḍāyatana). In Theravāda Buddhist thought, nāmarūpa refers to the four mental aggregates (nāma: the four mental khandhas) together with the material aggregate (rūpa). This forms the foundation for understanding human beings and other sentient beings.

The six sense bases (ṣaḍāyatana) comprise: the eye base (cakkhu), the ear base (sota), the nose base (ghāna), the tongue base (jivhā), the body base (kāya), and the mind base (mana). These bases are the mechanisms of perception that are aroused from nāmarūpa.

The relationship is presented according to Dependent Origination (Pratītyasamutpāda): nāmarūpa is the necessary condition for the arising and functioning of the six sense bases. Without nāmarūpa, the six sense bases cannot exist. Conversely, the six sense bases are the manifestation of nāmarūpa in the process of cognition and interaction with the world.

The sūtra typically offers a detailed analysis of the manner in which each sense base makes contact (phassa) with its object (ārammaṇa), giving rise to feeling (vedanā), leading to craving (taṇhā), and to actions bearing karmic consequence. This process repeats itself continually and constitutes the very mechanism of saṃsāra.

Practical Significance

This teaching is not intended to satisfy philosophical curiosity, but rather to enable practitioners to clearly understand the mechanism of suffering.
