I think the best way to really reach the light within you and optimise your spirituality is through meditation. When you focus inward you can travel over time, past and future, different worlds, other beings imaginary and magical. It is endless.
I first was inntroduced by an "Angel" a lady at work with whom I did not know particulary well a young solicitor who had recently joined the firm where I had been working.
I had been going through a traumatic emotional time and was confused and very unhappy, I had a screaming going on inside my mind, which now I realise was Spirit calling out to me.
