Is this world transient?

Question

Transient is this world; like phantoms and dreams,
Substance it has none. Grasp not the world nor your kin;
Cut the strings of lust and hatred; meditate in woods and mountains.
If without effort you remain loosely in the "natural state," soon Mahamudra you will win and attain the Non-attainment.
-Tilopa, "The Song of Mahamudra"

Answer 1

I'm not sure I know the answer, but there is a song that is about the same point.

"What if everything around you
Isn't quite as it seems?
What if all the world you think you know
Is an elaborate dream?
And if you look at your reflection
Is that all you want it to be?
What if you could look right through the cracks?
Would you find yourself
Find yourself afraid to see?

What if all the world's inside of your head
Just creations of your own?
Your devils and your gods
All the living and the dead
And you're really all alone?
You can live in this illusion
You can choose to believe
You keep looking but you can't find the words
Are you're hiding in the trees?"

-Right Where It Belongs, -NineInchNails

I love that song to death.
