Back in the days following my NDE – and I tried to speak openly about the essence of the incorporable ‘soul unit’ – I used the word ‘soul body.’ Many people would assume a physical or material vision of what I was trying to describe concerning the invisible nature of the ‘soul essence.’
On one of the pages linked above – it captures my understanding from the NDE when it mentions the difference between the ‘jiva-atma’ and the ‘param-atma.’
The idea that we are separated (split) from our ‘oversoul’ or from the Creator of life – is an illusion of the physical ego mind.
Much the same way as the illusion of separation from the ‘twin’ is a mental concept while incarnated in the physical form.
This is a parable somewhere about physical life being a reflection of the face of the soul on a body of water. As humans – we are but the reflection on the water. The true identity is within the soul that cast the reflection. Much is the same for the the twin. There is no ‘splitting’ of the ‘soul’ itself. The ‘soul’ just cast two separate reflection’s upon the water to create two ‘streams of consciousness’ that while incarnated ‘seems’ to be separate by the course of the ‘ego mind’ – yet in spiritual reality – they are together at all times on the other side of the veil that separates the physical and spiritual realities.
Plato used a metaphorical expression 2500 years ago and many people take that ‘splitting’ literally. In my opinion – it is a parable and not to be taken literally.
Through my experiences with it – the path back to the ‘twin’ is through what the Hindu’s call the oversoul (paramatma) and if your a Christian mindset – then it is through the union with the ‘Christ Consciousness’ within.
When I was a child and spoke to the ‘angelical messengers’ about the ‘twin’ aspect – they didn’t refer to it as ‘twin’s’ as much as they refereed to it as the ‘bride and bridegroom’ of the inner soul. In my opinion from my expereriences it is a metaphysical union more so than a material union.
