No. You could say mystery is at the heart of Catholicism: the mystery of the Trinity, of the Incarnation, etc. Mysticism, properly speaking, is a consolation, a direct experience of God.
But I can see why you don't believe in it.
And how does one know what god they are having contact with?
This is eastern mysticism that you defend.. a mystical meeting with god.
The god of this world loves the deception..at least he is god to someone
"now I realize what we all are. And if only everyone could realize this! I suddenly saw all the secret beauty of their hearts, the depths of their hearts where neither sin nor desire nor self-knowledge can reach, the core of their reality, the person that each one is in God's eyes. If only they could or see themselves as they really are. If only we could see each other that way all the time. There would be no more war, no more hatred, no more cruelty, no more greed… I suppose the big problem would be that we would fall down and worship each other."

This is not Christianity it is Pantheism
