Nothing to sell

If one observes the human world one will quickly see that it is based upon commerce. That is to say it is held together by the web of transactions on different levels that take place between people of all kinds. I buy a cup of coffee from you and you buy a pie from me. There is of course nothing wrong at all with that, and indeed it’s the way things work.
However when it comes to the question of understanding things at a deeper level, one has to ask oneself whether the same thing applies. If it does, all well and good. Go to the market and buy your understanding. But if it doesn’t, then what are you going to do?
Now it’s certainly not my job to tell you what you should do. And I’m not selling any ointments or remedies either if that’s what you are after. I have nothing at all to sell you.
