In PGM IV 1716 lies a very effective binding spell called the Sword of Dardanos, the man who founded the mysteries in Samothrace. The island is associated with the Goddess Hekate. It starts with an invocation to the God who created the universe. I have translated and it can be used as a strong invocation to Hekate Soteira or Hekate Panopaia or Hekate Pasikrateia and calling the aspects of Axis Mundi and Queen of the World.

Due to the nature of the ancient invocations, the Witch should have a deep connection with the Goddess, to make the invocation with all of his emotions and vibrating the vowels and pronouncing correctly the voces magicae with all of the energy.

For a complete structure of an invocation ritual see this and this. If you follow a magickal tradition, you already know what to do.
