The Trinity is One Spirit

We are all as One Spirit

There are three in the Trinity but they are as one, just as we as believers are one with God. In John 17 Jesus stressed the fact that He and God were as One and that we were as One with Him and God together as One. As One is stressed as several points are repeated more than once several times throughout John 17, known as the Holy Prayer. Read it again and notice how often points, apparently

important points, are repeated, like "One". This is all about the Spirit, One Spirit. 

There are psychedelic, and mushrooms etc., that may provide the hallucinations of oneness, but they are originated and drug induced within the body, rather than within the spirit.
