Gospel of Thomas, Logion 18 (Commentary)

(18) The disciples said to Jesus, "Tell us how our end will be." Jesus said, "Have you discovered, then, the beginning, that you look for the end? For where the beginning is, there will the end be. Blessed is he who will take his place in the beginning; he will know the end and will not experience death."

There is no time. The Alpha et Omega. The beginning in the end, the end in the beginning. Malkuth in Kether. Etc., etc. This is an age-old principle, and one that we can safely assume has true value among all traditions that hold it. However, let's also look at this in terms of Gnostic mythology. The Gnostic does not see Genesis as the beginning, but that which happened before that - i.e. the True God in the Pleroma, with Sophia and the Aeons, etc. Thus, to know about the end, the return to the Pleroma, we must know about the beginning, the true beginning. Indeed, it is with this knowledge of this creation myth, which the Gnostics held in great esteem, that the quest for the "end" (Gnosis, etc.) begins.

Gospel of Thomas, Logion 2 (Commentary)

(2) Jesus said, "Let him who seeks continue seeking until he finds. When he finds, he will become troubled. When he becomes troubled, he will be astonished, and he will rule over the All."

At the beginning of the path the Gnostic must take, he has not found Gnosis, so he must seek it before he can find it. When he finds it, he becomes troubled, because he is now exposed to the truth, and the truth isn't pretty: this isn't everything - there's more - we're trapped here in a lesser form, etc. This is effectively the awakening of the Gnostic to the prison of the Cosmos and the Demiurge. However, once he has become troubled, which is a necessary step, he will them realise that what at first seems like a terrible situation is actually a lot better than he first suspected. Yes, our Divine Spark is trapped, but before we awoke we did not know we had a Divine Spark, for our consciousness was dulled and tempered. Thus, the Gnostic then becomes astonished by the realisation that he can realise a great and monumental potential, the potential hidden within that Divine Spark. Then truly he rules over "the All" (the Fullness, the Pleroma) because, through his Divine Spark, he is the All, and thus is merely ruling over himself.
