The training of the faculty called "mindfulness" (Pali: "sati", Sanskrit: "smṛti," literally meaning "recollection, remembering") is central in Buddhism. According to Analayo, mindfulness is a full awareness of the present moment which enhances and strengthens memory. The Indian Buddhist philosopher Asanga defined mindfulness thus: "It is non-forgetting by the mind with regard to the object experienced. Its function is non-distraction." According to Rupert Gethin, "sati" is also "an awareness of things in relation to things, and hence an awareness of their relative value."
