To be able to distinguish between eternal and ephemeral is what is required in the seat of meditation. Viveka is used to find what's the difference between the changing and unchanging. 

We need to hold on to what's unchanging through the process of meditation. Another tool of meditation is jappa that helps with the process of thinking about the higher. All the steps in Bhaja Govindam has been training us to have the stamina, purity, and capacity to close our world, withdraw from the world, and think about the higher.
