Not merely by rites and precepts, nor by vast learning, nor by attaining concentration, nor by dwelling alone,

Na sīlabbatamattena — not merely by rites and precepts: sīlabbata are external rites and observances. Attachment to rites (sīlabbata-parāmāsa) is one of the ten fetters to samsara.

Bāhusaccena vā pana — nor by vast learning: extensive study (bāhusacca) is valuable but not sufficient by itself. Knowledge without practice does not liberate.

Samādhilābhena — nor by attaining concentration: even samādhi by itself is not enough. Concentration without wisdom can become quietism.

Vivittasayanena vā — nor by sleeping in solitude: solitude (vivittasayana) is a favorable condition but not a guarantee of liberation.

This verse lists four genuine practices that nevertheless, taken individually or without proper integration, do not lead to liberation. It prepares the following verse that completes the teaching.
