The Human Body
As a Homo Sapiens Sapiens, we have a physical body. Looking from the outside this is what we see and there are two types – men and women.
The picture to the right is of the physical body. In these pages I’m going to use the common model for human beings as having physical, emotional, mental and spiritual aspects. We should all agree that we have physical bodies, we experience emotions, and we have a mind which we use for thinking. The spiritual aspect is less well understood, but as we progress I’ll show that we are all familiar with qualities that I will categorise as “spiritual“. You could also consider these spiritual aspects as being higher emotional and mental brain functions, which we all have but don’t use to their maximum capability. Once you recognise that we have physical, emotional, mental and spiritual aspects, you’ll also realise that we spend most of our time looking after our physical body, and very little developing our higher mental and spiritual aspects. There will be more discussion on this in due course.
Why do we have a physical body?
We need it in order to interact with the physical world. Whether there is some greater purpose to life is something we have yet to discover, but in order to interact with the physical environment and have “experiences” we need a body to move around. Scientists will tell us that we need explore our environment and seek out shelter, food, and mates for reproduction. If you believe we are a spiritual consciousness, the physical body is what we use to interact with and experience the physical world.
Inputs from the physical world come via the senses (we have more than five!).
The data gets to the brain via the nervous system. The nervous system is also used to control our voluntary movement, and it also controls the internal body organs via the autonomic (involuntary) nervous system. There are also a range of automated reflexes that operate automatically for our protection.
More than simply the digestive system, the Enteric Nervous System (ENS) is often overlooked. It has a substantial neural network like the brain, and is capable of operating almost independently. A happy ENS is contributes significantly to the happiness of the rest of the physical body.
The nervous system is electro-chemical in nature. Electrical signals are transmitted using neurotransmitter chemicals and these are vital for a healthy body.
Whilst on the subject of the nervous system, neurotransmitters and the endocrine system, it is worth reviewing these along with the Kundalini energy and the Chakras from ancient traditions. It is also a good point to look in to alternative medicine like homeopathy and Ayurveda.
