Analysis. upa- + samā. upa (near, alongside) + samā (calmness, from sam- 'together' + the root of śamati 'becomes calm'). Literally 'tranquility approached' or 'pacification at hand'; in the canon, the supreme peace approaching through the stilling of all craving and aversion.
Etymology. The prefix upa- carries its spatial sense of proximity and access; sam- embeds the image of things coming together into stillness. Compare Sanskrit upāśama, and the Indo-European root *ḱem- (rest, peace) underlying samatha (calmness) and samādhi (collectedness). The compound idiomatically denotes the peace of Nibbāna as something attainable and near to the practitioner.
