In every school of Christianity, we see people who follow the same spirit, who do not want to speculate on what cannot be speculated about. "Negative theology" is an effort and practice to prevent Christians from being caught by notions and concepts that prevent them from touching the living spirit of Christianity. When we speak of negative theology, the theology of the Death of God, we are talking about the death of every concept we may have of God in order to experience God as a living reality directly.
A good theologian is one who says almost nothing about God, even though the word "theology" means "discourse about God." It is risky to talk about God. The notion of God might be an obstacle for us to touch God as love, wisdom, and mindfulness. The Buddha was very clear about this. He said, "You tell me that you are in love with a beautiful woman, but when I ask you, 'What is the color of her eyes? What is her name? What is the name of her town?' you cannot tell me. I don't believe you are really in love with something real." Your notion of God may be vague like that, not having to do with reality. The Buddha was not against God. He was only against notions of God that are mere mental constructions that do not correspond to reality, notions that prevent us from developing ourselves and touching ultimate reality. That is why I believe it is safer to approach God through the Holy Spirit than through the door of theology. We can identify the Holy Spirit whenever it makes its presence felt. Whenever we see someone who is loving, compassionate, mindful, caring, and understanding, we know that the Holy Spirit is there.
