Duality is broken and cannot be fixed. [1]
The only role of duality is to keep a Being asleep while its only redeeming factor is that it allows the experience of Re-Awakening into what's Real. Is it good? Yes. Is it bad? Yes. It's really only a limited way of looking at things, it's neither complicated nor frightening. When you really understand duality, there's no reason to hold on to it anymore. Duality exists only within the mind, the physical realm isn't even dualistic. What people call darkness is really just a frequency of Light outside the range of human perception. Duality is an attempt to conform a Multi-Dimensional Experience into a system of beliefs. It's inherently broken and cannot be fixed. It has to be thrown away entirely.
Any time you experience fear, anger, jealousy, engage in conflict, or hold a grudge, all those come from dualistic beliefs and feed into dualistic beliefs. Everyone that's a part of our society has been programmed with an enormous amount of beliefs the feed into duality. These need to be resolved before a Being can truly Awaken. A demon is an incomplete thought, and a dualistic thought is always half a thought. You can call these sin, attachments, or karma if you wish, at their most basic understanding they are all the same. It's something unresolved that you're holding on to,
I'll give you a technique for clearing emotional attachments. Here's the meditation:
Breathe
Okay, that's it. Nice meditation isn't it? Of course, for most people there's a lot more to the meditation than what they may see at first. You simply breathe, but you must breathe correctly. You must breathe Peacefully and Consciously. You must be stubborn enough to sit there and do it right. Don't shut anything out, don't close your eyes, be aware of everything you feel and see. When your mind starts to wander, focus upon your breath. Breathe. Breathe in everything around you. The greatest meditation is to live your life fully Present. You don't shut things out or dull the senses like some "meditations" try to do, you embrace everything and through this you grow bigger. Fake meditation is like watching a TV show, it's a pleasant distraction, but its effects are only temporary. True meditation changes you forever in every moment of Presence, you're always growing, learning, evolving, and expanding.
