Hello Alchemist,
We are sorry for the delay. We were on meditation retreat and have just come back.
You can invoke the Guardian of the Threshold in the internal worlds by praying to your Being in the Name of the Christ, by the Majesty of Christ, by the Power of Christ to bring this entity to you.
Or, if you are patient and trust your Being in your initial stages, you can allow Him to bring you the ordeal when you are ready.
