A recent spiritual teacher that has come to my attention recently is Nisargadatta Maharaj. Living normally most of his life, he went to see a spiritual teacher with a friend to help get him on his path. After an instruction to always remind himself of “I AM”, and repeat it when he get too attached to the problems of life, he allowed consciousness to come through and let his being merge with it. He became enlightened and shared his knowledge from the second story of his house. Here’s a documentary on him which I found very interesting. Enjoy!
