If we churn water will we get butter? We think that we can be happy in this material world, that by churning water, we shall get butter. Someone says to us, "There is no ingredient in the water by which you will get butter. All your efforts are a waste of time." We answer, "No, you have lost your mind. I shall go on churning for thousands of births!" If you churn yogurt or milk, then you can make butter. This world is devoid of eternal existence, devoid of knowledge and devoid of happiness. If you devote all your energy to this world, you will be in want of eternal existence, in want of knowledge and in want of happiness. Krishna is the embodiment of All-Existence, All-Knowledge and All-Bliss. We should worship Sri Krishna. In the Gita, Krishna says:

anityam asukham lokam
imam prapya bhajasva mam
(Bhagavad-gita, 9.33)

"You have forgotten Me and thus you have come to this non-eternal world." So start worshipping Him.
