I came to earth, but you mean things are impermanent.

Meaning: Things in the world can't stay the same forever; they are changing every day. Many things will change with the passage of time, reflecting a person's helplessness and inner acid.

But the only thing that won't change is our initial intention. As long as we believe in one thing, we shouldn't change it easily for some people and things around us. We should unswervingly go on and persevere until we succeed.
