The MIND-SPIRIT connection is a more complex part to understand, as SCIENCE representing the MIND and RELIGION representing the SPIRIT, have long been very separate and distinct domains of their own. In history, Religion was often disputed as discoveries of Science later revealed evidence to show that what beliefs that certain religions held at that time were incorrect. A well-known example of this is the misconception of the sun revolving around the earth. The fact that there are many types of religion eventually led to the question of whether God exists or not as a whole. Soon a new term called 'Secular' was used to denote the world of declining influence of religion and religious values.
Eventually, I realized in my research that the word CONSCIOUSNESS began to be a common denominator for the MIND-SPIRIT connection or the SCIENCE-RELIGION connection. In the secular world, the preference is not to use the name 'God' and 'Spiritual' seems to be a more politically accepted reference to someone who is religious so in our modern world, we can read an article entitled, "7 examples where Science meets Spirituality" The common ground is that both fields are seeking an understanding or explanation of the human being's awareness or consciousness. Let's start with the simple video below that presents a lucid way of understanding our CONSCIOUSNESS:
First learn the logic of who am I?
Here is a physicist who can use a simpler language to explain how Science and Spirituality are getting closer to each other :
Here is a long video which is more a sound recording of a podcast with the much revered scientist in USA that makes a lot of sense to me. It is a long video but if you have the sense to follow, it's worthwhile listening with all your Consciousness!
Michio Kaku is a very well known Scientist in the USA who can make complex science simple to understand. He does refer to the brain as a biological machine and has the theory that consciousness can be measured accurately as what science is supposed to do in terms of 'feedback loops'
