The Thomas Logia sound like Zen Koans sometimes

That sort of a comment has been quite common in the discussions around the Thomas gospel. By now we know enough to understand what happened to the Jesus tradition after his death: substantial embellishment. So no wonder that these early materials should have a different character.

Jesus may or may not have been to India in those first 33 years about which we know so little. We may not be able to know this for sure. However philosophically, since truth is one, and oneness is a non-dualistic concept, therefore it should not surprise if Jesus sounded like Buddha or like Advaita Vedanta at times. The explanation is not necessarily that he was exposed to those sources, although he may have been. People did travel. The summary of these different forms of belief system, from dualism to pure non-dualism is very well explained in Gary's 2nd book, Your Immortal Reality.

The philosophical point is perhaps more compelling. If truth is true, and all else is a lie, well, there are only so many ways you could express truth in words, particularly since words are by nature dualistic, and so you can only approach it, never state it explicitly. So at some level the most abstract expressions of wisdom teaching would have to sound recognizably similar. So to be "like the Buddha," Jesus does not have to be a Buddhist, or even have known about the Buddha. From that standpoint I am totally at ease around Gary Renard's frequent observation that A Course in Miracles is sometimes closer to Buddhism than to Christianity, although of course there are very dualistic traditions in Buddhism, but it does seem that in Buddhism more of the original non-dualistic teachings survived and even thrived at times.
