<P> According to Rhys Davids the first attested usage of the term samadhi in Sanskrit literature was in the Maitri Upanishad . </P> <P> The origins of the practice of dhyana, which culminates into samadhi, are a matter of dispute . According to Bronkhorst, dhyana was a Buddhist invention, whereas Alexander Wynne argues that dhyana was incorporated from Brahmanical practices, in the Nikayas ascribed to Alara Kalama and Uddaka Ramaputta . These practices were paired to mindfulness and insight, and given a new interpretation . Kalupahana also argues that the Buddha "reverted to the meditational practices" he had learned from Alara Kalama and Uddaka Ramaputta . </P> <P> The term' Samadhi' derives from the root sam - a-dha, which means' to collect' or' bring together', and thus it is often translated as' concentration' or' unification of mind' . In the early Buddhist texts, samadhi is also associated with the term samatha (calm abiding). In the suttas, samadhi is defined as one - pointedness of mind (Cittass'ekaggatā). </P> <P> Buddhagosa defines samadhi as "the centering of consciousness and consciousness concomitants evenly and rightly on a single object...the state in virtue of which consciousness and its concomitants remain evenly and rightly on a single object, undistracted and unscattered" (Vism. 84 - 85; PP. 85). </P>
