You are not a drop in the ocean but an ocean in every drop...said Rumi.
What did he mean by that... every cell in our body is intelligent to think and act.. We have 60 trillion cells in our body and our health depends a lot on the harmonic balance and cohesion of the cells with each other...
In the movie Eat, Pray Love, Julia Roberts visits a wise man in Bali, and he advises her not to try too hard to meditate.. in fact he suggests that meditation is nothing but smiling and the line that is a kicker, is " Smile with your liver "
If you believe that this is just a metaphor, lets look at the other end of the spectrum to prove just how crucial this is..
Let us say you hold a negative emotion towards somebody, something or some event in your life... each time you think of that your whole body re-lives the emotional upheaval of that association..
Your mind doesn't have a mind of its own, and doesn't know if the event is happening in real time or it is being replayed.. so it produces the same stress hormones.. each and every cell of your body starts feeling the same emotion of let us say "hatred" towards that event, person or experience all over again...
The body is not at ease.. this is a state where the condition of dis-ease sets in....
If you continue to live in that state, your cells are now getting conditioned to live in the same state...
The Upanishads talk about "Yatha Pinde tatha Brahmande" as is the atom so is the universe....
Health of a person, depends on how well all the systems of the body and the 60 trillion cells play the melody of harmony together..
When the cells are living in a state of hatred, they soon start exhibiting that with each other and killing healthy cells in the body...This leads to many forms of auto immune disease...
Like Rumi said.. you are not a drop in the ocean, you are an ocean in every drop...
Be careful of your thoughts, your feelings and your emotions...
Forgive people, not because they deserve it, but because you need it... Stay happy, stay healthy...
