In his 1960s sci-fi classic Stranger in a Strange Land, Robert Heinlein invented the word âgrokâ to describe a way of knowing that Martians employ. It means to understand something deeply and completely, so much so that you feel youâve become one with it. Because of its rarity, Martians donât just understand what water is or drink waterâthey grok it. Now grok has entered more common cultural use; âI grok thatâ is sort of like âI get that,â only more so. Itâs âI get thatâ on steroids. When you finally get down to making a choice from your narrowed-down list of alternatives, and youâve cognitively evaluated the issues, and emotionally and meditatively contemplated the alternatives, it may be time to grok it. To grok a choice, you donât think about itâyou become it. Letâs say youâve got three alternatives. Pick any one of them and stop thinking about it. Choose to think for the next one to three days that you are the person who has made the decision to pick Alternative A. Choice A is your reality right now.
