A Summary of the Srimad Bhagavata Mahapuranam-2-5.

Chapter-2. The Process of Creation-5.

This creation lasts as long as the life of Brahma continues.

When the hundred years of Brahma are over, there is cosmic dissolution.

 All the world will become liquid, as it were; there will be cosmic waters.

But the question will arise, what happens to the individuals, people like us, when everything in creation is dissolved during dissolution?

Do we attain liberation?

No, we do not attain liberation even if the whole world is dissolved, because liberation is freedom from desires of every kind.

A mere physical dissolution of things does not mean the dissolution of mental desires.

Just as sleep is not the end of the day and is only a commencement of the next day, in a similar manner, this cosmic sleep at the time of dissolution is a universal cessation of all activity but not a liberation of the forces of individualities.

They will all be dissolved into a seed form of subtle potentiality when the universe dissolves after such a lengthy period of time—namely, one hundred years of Brahma, the Creator. And then there is creation once again.
