What you call peace, is a certain kind of chemistry; joy is another kind of chemistry; anxiety is another kind of chemistry. Every human experience has a chemical basis to it. Recent research into the human brain has yielded some incredible results. An Israeli scientist spent several years researching certain aspects of the human brain, and he found there are millions of cannabis receptors in the brain! Then neurologists discovered that at different times of the day, if you closely observe the system and what happens with the brain chemistry, the body develops its own cannabis which satisfy the receptors in the brain. If a person is in a certain state of blissfulness or ecstasy, he produces these chemicals, which the brain is constantly waiting for. Even your brain is waiting for you to be blissful – millions of cannabis receptors are sitting there and waiting, not for you to smoke or drink or do drugs, but for you to become blissful.
When they found this chemical which goes towards the receptors, there was no name for it. The scientist had the freedom to name this newly found chemical. He wanted to give it a name which would be truly relevant. When he researched the Indian scriptures, to his amazement, he found that the Indian scriptures are the only scriptures which talk about blissfulness. No other religion on the planet talks about bliss. Religions talk about sin, religions talk about fear, religions talk about guilt, religions talk about punishment. But no other religion talks about blissfulness. So he called this chemical, which moves towards the cannabis receptors, “Anandamide.”
If you simply maintain your inner chemistry in a certain way, the body itself will produce these “bliss” molecules, whilst the nervous system will receive it. If you generate sufficient amount of anandamide in your system, you will be blissful, yet alert.
