We do not have to ask ourselves whether we are breathing, because breathing is not a concept. It is a perceived sensation and automatic action within the body. In the same way, Oneness will become felt within the body not as an idea but as a sensation - a perception of the same degree of reality as breathing brings to our physical senses.
The doorway is open. The passage has begun. Each consciousness that is willing can become more attuned to the underlying reality that is growing within human awareness. Let love extend further beyond the limits of the smaller self and its particular likes and dislikes and you will open the door further. Forgive everyone, and you will take another step.
This is the time of awakening. Blessings.
