so 'you' are unchanging and immutable?
also note that when there is an "i" there is also a "my" - as in "my responsibility"
which can be necessary, ok, and useful - but still only conventional
so,
do you say "i am happy" or "i am sad"?
'you' can not be both at the same time!
think about it
what is this "nature" that you speak of?
any action repeated many times (habit or ritual) tends to become natural.
this is nature.
