Every man ought to be inquisitive through every hour of his great adventure down to the day when he shall no longer cast a shadow in the sun. For if he dies without a question in his heart, what excuse is there for his continuance? http://www.rivendellvillage.org/Gangaji_The_Diamond_in_Your_Pocket.pdf --- Frank Moore Colby 

To know ourselves is our greatest achievement in our life.
According to Immanuel Kant, the Self is a form of consciousness 
that we experience especially when we reflect upon it. 
Hence it is that in the act of reflecting on our Self, it reveals itself to us. 

To know what you know in the core of your being without understanding is effortless.
The effort arises in having to understand it so that you can mentally know it and remember it,
so that it will be there for you if you get into trouble.......stop that search. []
The simplicity of the truth is what keeps it out of the reach of any concept,
including whatever concepts might be used in the moment to point to it.
It is out of reach because it is too close to be reached.
Concepts of the mind are distant compared to the closeness of the truth of who you are.
