Orthodox Definition
In the orthodox Theravāda operational framework, samatha is the practice of systematically calming the mind to cultivate one-pointed concentration (samādhi). Its primary functional goal is the complete temporary suppression of the five mental hindrances (nīvaraṇa) through the absorption states of jhāna.
Samatha works by binding the attention to a single, static conceptual object (paññatti), such as a colored disc (kasiṇa), the breath (ānāpāna), or a sublime quality (mettā). As concentration deepens, the mind shifts from the physical or preliminary sign (parikamma-nimitta) to the conceptual counterpart sign (paṭibhāga-nimitta), indicating that access concentration has been secured.
The commentaries place massive emphasis on the fact that samatha alone cannot produce liberation. It acts as an exceptionally powerful mental cleanser and stabilizer, creating a pristine, luminous laboratory of mind. Once stilled, this concentrated mind must be deployed to execute vipassanā (insight) to permanently dismantle the latent defilements.
