''Sthapana'' is establishing the same proposition on firm ground with the help of ''hetu'' (reason), ''drishtanta'' (instance), ''upanaya'' (correlation) and ''nigamana'' (conclusion). First there is proposition (''pratijna'') and then establishment (''sthapana'') because what can be established (nothing) in absence of proposition? For instance, ‘''purusha'' is eternal’ – this is proposition, reason ([[hetu]]) is - ‘because of not being created’; instance (''drishtanta'') is – ‘as sky’; correlation (''upanaya'') is – ‘as the sky is uncreated and is eternal so is ''purusha''’; conclusion (''nigamana'') is - ‘therefore, ''purusha'' is eternal.’[31]
