In Judaism, we don't need intermediaries to pray to G-d.
That's one of the main lessons learned in the story of Chana's Prayer in Shiloh.
I live in Shiloh. My house is less than two kilometers, just over a mile from Shiloh HaKeduma, Ancient Biblical Shiloh. Shiloh was the spiritual and administrative Capital of the Jewish Nation for 369 years, from the time Joshua brought the Jewish tribes into the Holy/Promised Land to the time when Samuel became our most important Prophet.
Many people still come to Shiloh to pray. We pray at Shiloh because there was and is a direct line to G-d here. The site isn't littered with tiny pieces of paper. And there are no tombs and graves of "holy men."
One of the reasons that Chana's method of praying had Eli The High Priest confused (he accused her of being drunk) was that she didn't ask him to intercede and pray for her. Chana spoke directly to G-d. She moved her lips but was silent. G-d hears via the heart and lips. You don't need to turn up the volume, shout, clap etc.
The birth of Samuel, later known as Samuel the Prophet, was proof that her prayer method was the correct one. That's why the Jewish Laws of Prayer are based on Chana.
