This Gospel of Thomas was found in the 1940's and translated. It was not manipulated by the PTB, and is said to be the closest to the truth that was written.
Here is one verse:
He said to them, "Anyone here with two ears had better listen! There is light within a person of light, and it shines on the whole world. If it does not shine, it is dark."
34 Jesus said, "If a blind person leads a blind person, both of them will fall into a hole."
For this reason I say, if one is whole, one will be filled with light, but if one is divided, one will be filled with darkness."
