Intent phrase: Shatter Time.
After gnostic rearranging:
Construct this sigil upon a timepiece that you don't mind destroying. Begin the ritual with the banishing of the Speaking of the Way, and a Vortex Rite. as this particular working will require a well constructed Vortex.
Once this all has been completed, achieve gnosis and charge the sigil. Once the appropriate levels of energy have been generated, destroy the timepiece and the sigil, in the most violent manner possible. Kinda like OfficeSpace and the fax machine.
You should notice the seperations between yourself and future and past selves decreasing. In other words, what you learned in the future will be accessible, but so will flaws that you once had. You must be prepared to overcome many of them again (which should resonate in the past as well).
Try practicing divination in conjunction with this, I'd be intered to see what affect future insights have.
