All living organism from a single cell through a pacific clam to a human are receptive to information. Take a single cell, for example: it's completely open to 'The Field' which makes it the perfect antennae but the lousiest processor. This is most apparent when you and I were a single cell in our mother's womb - we picked up everything around us but we hadn't developed enough to process the information we were receiving, so we weren't able to make sense of any of it.
The first trimester of your life in your mother's womb is the source of profound imprints that affect you throughout adult life. You were like a open antennae unable to filter what you were receiving, and what you picked up while you were in this simple and undeveloped state was raw emotion. Most mothers will agree that during their pregnancy they experience a wide variety of powerful emotions and psychological changes. These can range from anxiety and fear as she begins to understand the reality of her situation. In addition, because of fluctuating hormones, mothers may experience sadness, irritability and irrational behaviour. There are also feelings that range from joy and acceptance of a beautiful experience through to hostility and rejection of an unwelcome situation.
Whatever your mother's emotional experience during your first few months of life you were strapped into her womb like being strapped in to a roller-coaster - but with one big difference: you would have experienced the emotions as your own. The reason for this is because you hadn't developed a brain to help you understand the situation and recognise that these feeling were someone else's.
So if mother felt love and acceptance then this feeling will be with you all your life and is likely to result in you having a loving and accepting personality. A more difficult start is to be bombarded with negative feelings. Then you go through life with a constant deep-down feeling that either the world is a hostile place or there's something wrong with you.
These fundamentally deep and mostly unconscious beliefs that we form at this stage form the basis of our attitude towards life. So if you're loving and accepting then it's a good bet that your life in mother's womb was likewise loving and accepting.
However, that's not the experience that many of us had, for our mother's experience of life would have been far from perfect, and during the first trimester especially those fundamentally deep and unconscious beliefs about the world would have been laid down. Hostility and rejection will be translated to feelings of paranoia or inadequacy and a belief that the world is a hostile and rejecting place or that everyone else is better than you.
The good news is as adults we're all capable of self-reflection - we're able to look into ourselves and check out whether all those beliefs we've accumulated are useful/true or not.
