Dear Mohammed,

Thank you for your interesting question. I touch on the subject in my thesis, but maybe from a slightly different perspective as I put the heart as primary. Here is what I say:

"Insights Regarding the Pineal Organ and the Heart as a Possible Oscillating System

 I have touched on the pineal organ and suggested that together with the heart, it may act like a crystal oscillator system. In this way I feel that messages could be communicated in a more subtle way throughout the body. I suggested this could be related to somatogenesis and also to overall body functioning. I also hinted this could be how information from outside the system is communicated to the system. Obviously, this might work both ways and be a way the organism communicates with the outside world. This level of communication would go on below our level of consciousness. However, I feel that one can become conscious of this system and use it consciously. . ." (Lindhard, 2016, p. 195–196).

Regarding sight - well I feel that when we "see" perfectly we see through the pineal chakra "- this is connected to how we see but goes far beyond it and it also involves the heart system. When we are connected every cell in our body "sees". This has been shown in teaching blind people how to "see". This is based on esoteric knowledge but I am not sure how much scientific research is published on this, but it has been undertaken in Russia, China and in USA: 

Warm regards - Tina
