I was recently reading the Satipatthana Vipassana by Venerable Mahasi Sayadaw
http://www.accesstoinsight.org/lib/auth ... el370.html
I have a question regarding the “Nothing is permanent”. Near the end of document Mahashi Saydaw
says :
“On continuing the practice of contemplation for some time, there will be considerable progress in mindfulness and concentration. At this high level it will be perceptible that on every occasion of noting, each process arises and passes away at that very moment. But, on the other hand, uninstructed people generally consider that the body and mind remain in a permanent state throughout life, that the same body of childhood has grown up into adulthood, that the same young mind has grown up into maturity, and that both body and mind are one and the same person. In reality, this is not so. Nothing is permanent. Everything comes into existence for a moment and then passes away. Nothing can remain even for the blink of an eye. Changes are taking place very swiftly and they will be perceived in due course.”
What is not clear to me is the phrase “Everything comes into existence for a moment and then passes
away”. In what way does he mean that? For example if we consider the feelings, when an object
touches the sense organ of the skin, I can understand that the feeling that arises that moment was not
there before, and that when the object is removed, the feeling passes away. When he says that
“Everything comes into existence etc” is ordinary matter also included?
Are all physical objects in a continuous state or arising and passing away independently of our
senses, and if they are, where are they arising from, and where are they passing away to?
Is that what he means?
Thank you.

(Gas, liquid, and solid?) I think that's been known for quite a long time. Also... I think the definition of "matter" is still problematic in the physics. (Mass on the other hand has a definition that is generally accepted.)
