Christians, can you explain doctrine of trinity ?

Not a doctrine but an explanation of the Truth which is ONENESS of Spirit and how we relate to the Almighty God. The Living God the Father impregnates His Wife (his Holy Breath or Spirit) with the Living word (the son). The Father speaks the Living word (the son) using his Holy Breath (Holy Spirit) to carry the word just like we use breath to carry our words. The Father speaks using the Holy Spirit so the son speaks using the Holy Spirit. The Father is Spirit, the son is Spirit and the Holy Spirit is Spirit and all 3 together are the Holy Spirit. It speaks of the oneness of Heaven and all those who are like Jesus will speak only from the Holy Spirit and everyone who enters Heaven shall be one with Holy Spirit. The self is an illusion and does not exist in Eternity. There are no rewards in heaven other than greatest reward of being One with the Eternal One our Loving Father the Imageless Spirit of Life. It begins right here right now for those who choose to know the Eternal One by humbling the self identity. The physical universe is an illusion and time and distances of space are relative and that creates a fragmented and limited mind that causes us to try to measure everything using relative units of measure.
