The answer
This did not happen at all. There is no evidence or reference whatsoever that the Master Christ went to India, or elsewhere in the Far East.
Holy Scripture does not mention that the Master Christ travelled any further than Egypt at the time of His infancy, being accompanied by St. Joseph the Carpenter and Holy Virgin Mary. Their journey was to flee from King Herod, who had ordered the slaughter of any child two years old and under (Matt. 2).
Holy Scripture mentions also that, during His general ministry, He had travelled to coasts of Tyre and Sidon in Lebanon, where He preached and performed miracles (Matt. 15; Mark 7).
As for the duration between the age of 12 to 30 of the life of Our Lord Jesus Christ in the flesh on Earth, they were spent in the city of Nazareth in Palestine, where He was known by the people of His city. He worked amongst them as a carpenter, and they knew His mother. This was until His thirtieth year, which is the age of maturity for men, according to the Jews. No one can be accepted as a member of the Jewish council, or to become a teacher (i.e. rabbi), unless he is of this age of maturity, or manhood.
