So behind this material energy... Material energy, just like we see, there is cloud, there is thundering sound, there is rain. And from the rain, there is crops, there is food grain. Then we eat those food grains. Annād bhavanti bhūtāni parjanyād anna-sambhavaḥ. Then, yajñād bhavati parjanyo yajñaḥ karma-samudbhavaḥ (BG 3.14). These things are already stated. Everything, the origin is the Supreme Personality of Godhead, Yajña. Yajñaḥ karma-samudbhavaḥ. Yajña means we have to satisfy the Supreme Person. That is called yajña. And this process can be executed when the human society is very regulated. Regulated means there must be division of these varṇas and āśramas. Varṇa means four varṇas: brāhmaṇa, kṣatriya, vaiśya, śūdra. And four āśramas: brahmacārī, gṛhastha, vānaprastha, sannyāsa. They have got their respective duties. So unless the human society is divided into these eight scientific divisions and everyone acts according to his position, there cannot be any peace in the world. That is called varṇāśrama.
Varṇāśramācāravatā puruṣeṇa paraḥ pumān, viṣṇur ārādhyate... (CC Madhya 8.58). The ultimate goal is to satisfy the Lord, Supreme Lord Viṣṇu. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). But the foolish people, they do not know. Their ultimate interest is how to satisfy Viṣṇu. Viṣṇur ārādhyate. So when there is dharmasya glāniḥ, then Lord Viṣṇu, or Kṛṣṇa, by His incarnation or personally, He comes. Therefore it is said, yad yad vidhatte bhagavān. But because He comes to paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8), He has no anxiety. Svacchandātmā. And He does by His own internal potency. He does not take anyone's help. That is Kṛṣṇa. That is Bhagavān. Na tasya kāryaṁ karaṇaṁ ca vidyate. He has got so varieties of energies that everything is done very correctly and perfectly.
