Unless you have experienced it, you cannot understand it.
You simply have heard someone say it.
But that is okay. Keep it at the back of your mind and just live simply and naturally. Know that the highest flowering in life is being in love and acting through love.
You may not feel love all the time and everywhere. Many times we try to feel love as an emotion. Love is not an emotion, it is our very existence.
So, ‘God is love’ should not be taken as being more emotional.
You have just heard somebody saying you are God, okay let it be! Just go through your experience. You are nobody, you are an expanded awareness; know that much.
First understand what you are not then what you are comes to you spontaneously.
