Modern Hesychasm in Christianity

There is a hindu contemplative tradition called self-inquiry, where a seeker of God asks "who am I?" to expose the person as unreal (a collection of self-image, body, identification, etc.) The experience of witnessing the person exposes the true witness as beyond the person, beyond quality, and as absolute knowing itself. God alone is, and the person is but an imaginary extension. I'm looking for Christian traditions that follow a similar path toward an experiential discovery of God. I found that the term is Hesychasm (going into one's "self"), but it looks like outside of Eastern Orthodox it's a dead tradition. The closest work I've found to this understanding is the Cloud of Unknowing The Philokalia has also been recommended (written by the "watchful" saints). I've also been looking at the Franciscans ("What we are looking for is what is looking" St Francis) and the Trappist Centering Prayer. Also someone pointed me to this scripture: "I am who I am" (Exodus 3:14): Moses asks what he is to say to the Israelites when they ask what god has sent him to them, and Yahweh replies, "I am who I am," adding, "Say this to the people of Israel, 'I am has sent me to you.'"
