The Book of Thomas the Contender
From the Nag Hamadi book "The Book of Thomas the Contender", words supposedly spoken by Jesus to Judas Thomas.
"Now, since it has been said that you are my twin and true companion, examine yourself, and learn who you are, in what way you exist, and how you will come to be. Since you will be called my brother, it is not fitting that you be ignorant of yourself. And I know that you have understood, because you had already understood that I am the knowledge of the truth. So while you accompany me, although you are uncomprehending, you have (in fact) already come to know, and you will be called 'the one who knows himself'. For he who has not known himself has known nothing, but he who has known himself has at the same time already achieved knowledge about the depth of the all. So then, you, my brother Thomas, have beheld what is obscure to men, that is, what they ignorantly stumble against."
These words seem to echo the things I say also. In knowing the self, one knows the all. It also seems to indicate that Jesus indeed had an experience of cosmic consciousness, which changed him and gave him the ability to discern the truth about our existence - and proceed to talk about it at length apparently.
As I do also. As a sidenote, it is irritating that they all are called by the same names. How many Thomas'es and Judas'es was there really?
