Prabhupāda: Another example: this finger takes some foodstuff and gives to the stomach. So when the stomach is satisfied, the finger is satisfied automatically. It does not require to take separately any food. But the karmis are trying to enjoy themselves just like the finger. If it takes a nice cake and if he thinks that why shall I give it to the stomach? So it cannot eat. It simply spoils. That's all. So we are spoiling our energy without Kṛṣṇa consciousness. And therefore you are being subjected to the laws of transmigrating from one species of life. We are simply spoiling our time and energy. So if we take to Kṛṣṇa consciousness that is the proper utilization of our energy given by God.
