All is one and you are the One. You can have the experience that you are free because you no longer identify with a mind, body, and personality, but only rarely, other than having a vague sense of Oneness, does the individual have a really clear perception of the perfect unity that is actually inherent in awakening. It is much like when you have a dream at night and are identified with some character and think you are different from all the others.
When you wake up from your dream in the morning, you realize that you are not the character in the dream. You are the dreamer. Everything in the dream came from you. This is a metaphor for spiritual awakening because, when you wake up spiritually, you realize you are not the body-mind. But what is usually missed is that you are the ultimate source of the entire dream. I think this is pretty easy to understand. In one sense, you see that you are not anyone, but in the other, you realize that you are the source of all.
Why is this so important to realize? Because of the implication inherent within awakening, which is where you find all the value of any true spiritual revelation. You are the ultimate source, and everything is perfect unity and everything out there is actually you, equally. So inherent in this revelation of unity is the realization that there is no such thing as an "other."
There is no one else because it is all ultimately one's own Self. I've known people who have had this perception, and then the first thing they do is return to living life as if there was an other. They live life as if there is a personal me and a personal you, even though they have experientially glimpsed that this is not true. When you look into your own experience and ask how spiritual realization works, you start to realize so much of what we talk about is just ridiculous— it's the blind leading the blind.
This that you look at and call teacher is your own creation, it is your dream, and you are creating it at this moment. If you let yourself become aware, you will become aware that you are creating it and that the separation between the person listening and the one speaking is only appearance. If you are awakened, you have seen this clearly. But the conditioning can pull you back into the dream. This doesn't matter. You have to just keep questioning the dream itself. Spiritually speaking, the question, "What am I?" is the question that goes right to the heart of things.
The infinite intelligence is actually what you are, but you have to be serious enough to find out for yourself what is true. In order to do this, you have to open to the possibility that all you have learned is wrong. Otherwise, how can you discover what actually is?
When you become completely open, the Truth becomes the most apparent thing. Spiritual people always think the Truth is hidden from them. It is not hidden. What gets in the way is the idea of what it is going to be. Find that place of what actually is. There is only the One manifesting as everything.
Ponder and meditate on this until you realize it for yourself through and through. Wake up to what you are.
