 This basic term may have been extended with descriptions of the eightfold path, itself a condensation of a longer sequence.Some scholars believe that under pressure from developments in Indian religiosity, which began to see "liberating insight" as the essence of "moksha", the four noble truths were then added as a description of the Buddha's "liberating insight".According to Tilmann Vetter, the Buddha at first sought "the deathless" ("amata/amrta"), which is concerned with the here and now.
