In Jainism, caffeine is generally discouraged because it is a stimulant and can affect mind and self-control, which are central to ahimsa (non-violence) and tapas (self-restraint). The monastic code (Das Lakshan) explicitly restricts substances that disturb discipline, which includes coffee. Among lay Jains, practices vary by family and tradition, but many communities still prefer to avoid stimulants like tea and coffee to uphold mindfulness and non-violence. Both Digambar and Śvētāmbara traditions emphasize restraint and self-discipline, though exact rules for lay practice can differ by guru or local guidelines.
