Saguna becomes Atma; Father, Son, Holy Spirit

And this Atma is nothing but whose presence? It is God's presence. So, when I would have had a son called Sarguna, and Sarguna also was too big for us to fathom. So, Sarguna said, let me make myself available to myself as the Atma itself. What is this? We see that religion are different, but they know because this is the father's son and the Holy Spirit. So, the way back to true understanding is through the Atma. Thank you.
