There is only one Truth. The Truth is that Hashem is our G-d, Hashem is the only G-d, there are no others, and that He is One. The Truth is also that He gave us his Torah, so we could learn from it, and walk it's peaceful paths, and be the best Jews we can possibly be. The Truth is also, that Hashem has granted the world tzaddikim, righteous people who can help clarify the Truth for us, help us learn, live our lives as they should be lived, and who can help us pray, and above all, help elevate our souls. But, these people are not G-d, they only help us to serve G-d. The Truth is simple, it is sheker (falsehood) that is complicated.
"There may be many lies, but there is only one truth." Likutey Moharan I 51
