both... to different degrees and different levels etc.
Life is unchanged.<br />
Human being changes himself thoughtfully,<br />
from bad to good and vice-versa.<br />
The world changes itself naturally from forms to forms,<br />
from old to new and vice-versa.<br />
They have influences on one another,<br />
but none can change the other.<br />
As man changes, the world is changing <br />
with him, and not by him.
neither is exclusive of the other / change in human beings and change in life are pretty much the same thing.
Yes for both sides. ^_^ Technically humans are the ones making decisions and are the ones acting on the situation but Life is a strong motivation to influence what humans are capable of.
