"Krishna is the supreme witness sitting within your heart. He notes down what you are thinking and what you are doing. He also gives facility. If you want to do something to satisfy your senses, Krishna gives the facility for that action. That is stated in the Bhagavad-gita. Sarvasya caham sannivistah: 'I am sitting in everyone's heart.' Mattah smrtir jnanam apohanam ca: 'From Me come remembrance, knowledge and truthfulness.'
In this way, Krishna gives us a chance. If you want Krishna, then He will give you a chance to have Him, and if you don't want Krishna, then He will give you a chance to forget Him. If you want to enjoy life forgetting Krishna, forgetting God, then Krishna will give you all facility so that you can forget, and if you want to enjoy life with Krishna consciousness, then Krishna will give you the chance to make progress in Krishna consciousness. That is up to you."
