The Thunder, Perfect Mind is a poem discovered among the Gnostic manuscripts at Nag Hammadi in 1945.

Thunder Perfect Mind (the title is, more accurately, The Thunder - Perfect Intellect), takes the form of an extended, riddling monologue, in which an immanent saviour speaks a series of paradoxical statements concerning the divine feminine nature. These paradoxical utterances echo Greek identity riddles, a common poetic form in the Mediterranean. There are some translations to the right from the same section of the poem. Line numbering is different in different translations.
