The main character, from my memory, in Robert A. Heinlein best-selling 1961 book Stranger in a Strange Land, is about to step onto some grass. As he has just come from mars, where if I remember correctly, he was the offspring of an earthling and a martian, he had a supersensitivity. Instead of stepping on the grass, he pulls back, noticing that "grass is a living thing", so he doesn't want to step on it. Then, as the message gets through to him, he says "oh, I grok that grass is for walking on."
To grok (sounds like 'grock') is to "intimately and completely share the same reality or line of thinking with another physical or conceptual entity." And it has grown to be used in some training atmospheres as "do you grok that?" It is an extension of great understanding.
However, it is deeper than understanding, as a "grokked concept" becomes part of the person, as if it is merged into him. It is to so thoroughly understand and related to that it is fully integrated into the person's doing and thinking and, in a sense, being. Once understood, as a part of him, the concept is automatic and inherent in who he is and what he does.
It is going beyond "mere" wisdom, to the next levels. Wisdom is a very deep understanding and a knowing of how something works and the ability to make it work or operate it.
Perhaps the closest thing to it happens at the point where a person becomes a Master at something, where it is so natural and so much a practiced part of him but one where there is complete awareness around it - and it becomes him. That is the point, and maybe it continues too, where he has grokked it.
I suggest that what you want to do, as long as you're here in this life and have nothing better to do, is grok "life" and its components, to integrate into your being a Master Of Life, A Champion Of Living Life.
