I'm glad someone out there took this project. There really isn't much outside of Egypt on the topic and it would be interesting to know more.
What's to know?
We know from scripture that Jesus was with his family in Egypt until shortly after Herod's death, when an angel then commanded them to return to Israel. Since Herod died in 4 AD, we can assume that Jesus had not learned much of anything from anyone in Egypt in those 4 years. And since he was in fact the Lord incarnate, the idea that he would have to learn anything from anyone about spiriual matters is quite laughable. Much is made about the "missing 18 years' from 12 to 30 as well, but since Jesus was already teaching Levites and religious leaders in the temple when he was 12, this idea that he 'went to India to learn from the Hindus' or variations of that theme are equally ridiculous.
