Why has Dr Mikao Usui himself not brought through these new levels?
As it was explained to us by Higher Consciousness:
"As you are aware, Dr Mikao Usui no longer resides in your Earth realm. He has however, through our dimension, been involved in the process of developing these new levels. Although it may sometimes seem incomprehensible from the Earth plane; the consciousness of all dimensions is eternally connected and in this way, many high energy beings have come together to manifest these higher levels.
Dr Mikao Usui and Hawaya Takata have offered their blessings and endorsement of these new energies and are still very much so connected with them. In this way, you may still feel their connections when using the new symbols. Do not live in doubt, simply surrender and all will be unveiled."
