Did Christ consort with mystics? In the time of Christ, were there mystics, Jewish or otherwise, with whom Christ consorted before or during the time of His ministry?

By "mystics" is meant those comparable to Sufi mystics, who seek hidden spiritual truths by various means, and not those who perform acts the results of which are unexplained by temporal science ("magicians".)
In John 2 (NIV), it says:


  23 Now while he was in Jerusalem at the Passover Festival, many people
  saw the signs he was performing and believed in his name. 24 But
  Jesus would not entrust himself to them, for he knew all people. 25 He
  did not need any testimony about mankind, for he knew what was in each
  person.


In the KJV, it says:


  23 Now when he was in Jerusalem at the passover, in the feast day,
  many believed in his name, when they saw the miracles which he did.
  
  24 But Jesus did not commit himself unto them, because he knew all
  men,
  
  25 And needed not that any should testify of man: for he knew what was
  in man.


While this does not say outright that Jesus did not consort with mystics, it attacks the very basis of the mystical approach to knowledge. 

In the Socratic method of the Greeks, a teacher would ask questions and the pupils would answer them and the process would lead them to truth. Jesus needed no such dialogue to establish or explore truth. He did not need a school of researchers to perform experiments and write papers that he could attach his name to. All truth originated within Jesus.
