Regardless of Yeshua going to the East, he was teaching Dharmic principles - as he was an Avatar sent from Heaven.

• When Yeshua was saying about "letting our works shine", that is equal to karma (Matthew 5:16).
• The idea of teaching here is like Middle Earth (Gehenna), and we're down near Hell, is equal to the concepts of the Maya (Matthew 23:15).
• His earlier followers (the Ebionites), were vegetarian, and didn't drink alcohol.

The problem with understanding where Yeshua was coming from, is it's tainted by Christianity (Paul + Simon), and the false Gospel of John being made up by the Sanhedrin - where they have a more Pharisaical religious outlook.
