Didn't Jesus learn from Buddhists in India?
No. The story comes from Nicolas Notovitch's book of 1894, refuted within two years. The Gospels show Jesus grew up in Nazareth and taught from the Hebrew Scriptures.
In 1895 J. Archibald Douglas went to the monastery where Notovitch claimed to have seen a manuscript about Jesus; the head lama said there was no such text and no such visit. The people of Nazareth knew Jesus as the local carpenter and were astonished at his teaching.
2When the Sabbath had come, he began to teach in the synagogue, and many hearing him were astonished, saying, “Where did this man get these things?” and, “What is the wisdom that is given to this man, that such mighty works come about by his hands? 3Isn’t this the carpenter, the son of Mary and brother of James, Joses, Judah, and Simon? Aren’t his sisters here with us?” So they were offended at him.

16He came to Nazareth, where he had been brought up. He entered, as was his custom, into the synagogue on the Sabbath day, and stood up to read. 17The book of the prophet Isaiah was handed to him. He opened the book, and found the place where it was written, 18“The Spirit of the Lord is on me, because he has anointed me to preach good news to the poor. He has sent me to heal the broken hearted, to proclaim release to the captives, recovering of sight to the blind, to deliver those who are crushed, 19and to proclaim the acceptable year of the Lord.” 20He closed the book, gave it back to the attendant, and sat down. The eyes of all in the synagogue were fastened on him. 21He began to tell them, “Today, this Scripture has been fulfilled in your hearing.”
