Relation of inspiration and angelic talk in the knowledge of Shiite Imams

Shiite Imams have a high degree of knowledge which transcends human knowledge although this knowledge is not an innate and independent one but an effusion so the Imams receive these kinds of knowledge from a different source. Inspiration and angelic talk are among the important sources of the knowledge of the Imams that attention to them and exploration of them shows their relation to each other. The question of the present article is that while inspiration and angelic talk are kinds of mystic unveiling and intuition, so what is the difference between these two? Perhaps inspiration and angelic talk have a single originality and only because of different observations and attitudes from different angels, they have been considered differently. Also, the essential doubt according to which to use from these two sources are incoherent with the inherence of the knowledge of Imams from the noble Prophet and nessasitates the knowledge of the household of prophet to be more than the prophet himself, will be answered.
