In shallow men the fish of little thoughts cause much commotion. In oceanic minds the whales of inspiration make hardly a ruffle.
~Sri Yukteswar Giri

So what do they mean?
In a mind with very little control, every thought will flow out of them – these are the kind of people who interpret and come out of their own , very flawed explanation of all they read. They will comment on everything.
Those with immense depth, even a magnificent thought is submerged back within. Staying within with immense peace. They do not explain or discuss even when it is immensely revealing. Those giants wait patiently for one disciple to be worthy of Listening to the Profound truth
The photo says that if you truly want to be divinely guided then you must have learnt to calm your mind completely. You no longer have your own thoughts. They remain ever so peaceful with absence of any thought !
That my friend is Peace. Any thought is violence. Thus, like I said in my previous blog a few days ago, any thought, conflicting thoughts is violence. It is a violent protest against the divine peace that is present everywhere. So be established in non violence. In peace. Without thought
