BIG question – simple answer.
The nature of Reality is that it is REAL
Hmm… I hear a disappointing groan… What did you expect, some long-winded reply with references to classical texts and ‘big’ names in philosophy and spirituality? Nah.. why rely on the dead minds when you’ve got your own: alive, thinking, ticking, questioning curious mind??
However… it is up to you to figure out what is NOT real. Starting from the contents of your mind, which, like in Hercules and the Augean stables tale – can be cleaned out so comprehensively that you will be left wondering how you could stand the smell of the faeces before.
Now, those falling trees…. does a falling tree make a sound in a forest if there is no one to hear it? Sure, absolutely. The tree absolutely makes a sound regardless of who is there to hear it. The sound is a movement of the air particles. When the tree falls – the particles move, and the sound is created. Your ears are surplus to requirements.
In the same way… Just because there is no one to see the atmosphere on Venus – does not mean there is no atmosphere on Venus. I hear it is pretty toxic, don’t you find it ironic? And in reverse.. just because you believe something is NOT there – doesn’t mean it does not exist. Like viruses, for instance. You cannot see them, but can you deny they exist?
“Ewww!!! Don’t sneeze on me!!”
You will be able to crack every koan once free from the blindfold. They all rely on common sense, not on book sense, i.e. borrowed wisdom.
Disclaimer: Fear not! When I decide to write a book – I will of course make it all sound much more complicated and mysterious, in line with the head scratching ‘tradition’.
