The best method I know of to raise one's personal consciousness is through meditation. In fact, I would say that it is the only way. Meditation doesn't have to be sitting cross-legged on a cushion, of course. Whenever you apply a relaxed awareness to what you are doing, you are meditating.
Meditating on one's own conscious awareness is a fairly high-level activity. It is simply this: focus on your mind, gently, seeking the origin of your own awareness. Doing this, you are returning the energy that emanates from that place back to its source and you thus increase its power. This is not easy to maintain and all sorts of thoughts will distract you but as a small daily practice it will build over time. Just a few minutes a day is of great benefit.
A good time to do this is when you have a song or tune stuck in your head. You know, especially when it starts to get irritating. Focus your attention on the place in your brain where the music seems to come from. You will know that you have found it when the music stops. And you will know when your attention slips when it starts up again.
Practice of this kind will increase your consciousness of your own consciousness and you will begin to realise your independent source, the origin of yourself. And the flow on effect is a greater concern beyond that self as you realise that everybody else, all people and animals and I believe plants too, share that basic level of consciousness. It is one thing that we all have in common; and however more developed our consciousness may be than a frog's or tree's, it is the very thing that we can call our humanity, our being, our essence.
