I am a thing - specifically an animal body. There is no mind, only body which performs the mind.
Discussion
Mind is like bitcoin since it is not a thing it can appear as all things. This is where we come to the teaching of the 2 truths (relative or provisional and absolute). Where is the inherent thingness of the body? Can you find anything that has self existence, or is it compounded of many things which themselves cannot be found to have inherent self existing qualities?
For example a tree is made of many causes and conditions particles, atoms, molecules, come together and form complex systems from dna and all the other products of particle, atom, and molecule. Then a seed must form, conditions for the seed to grow must exist. Water, sun, ground, ect.
Basically what I'm saying is that one cannot find inherent thingness to anything even particles, quarks, strings, ect. Even our observation of these is limited through the five senses and mind which we interpret them through.
Yet we can recognize that all life systems are interdependently originated through this process of logic.
Simply because something can be divided or analyzed in its parts doesn't make it "not a thing"
This cosmos is one thing
This planet is one thing
This body is one thing
This fingernail is one thing
Yet ultimately boarderless, things being aspects of the whole. The organism needs this information to survive in relativistic existence. So the mind attempts to divide an ultimately indivisible reality into parts, which is useful to that end.
What mind?
Since it's not a thing I can't point it out. Lol for what is changeless in the midst of change.
I have a koan I can share on this. It's one of my favorites. I can also share a short video on direct recognition of rigpa. But it's work one has to do for oneself.
Basically Mind is just a convention for talking about what is here before thought and sense perception. Hope this is helpful!
