O living entities! You have become entangled in the network of illusion, so that you are always engaged in useless activities. Your life may end at any moment. Just consider this once. You have been wandering in this world, under the control of your material desires. But what kind of happiness are you looking for? Who are you? Where were you before this lifetime? Why have you come here? What have you accomplished and where will you go after death?

-Selected Text from Gitavali by Bhaktivinoda Thakura

You are always engaged in useless activities. Your life may end at any moment! Just consider this once
