Cause of all causes. When one is fully aware of this, he is brāhmaṇa Vaiṣṇava. Brahma jānātīti brāhmaṇa. This brahma jānāti means paraṁ brahma is Kṛṣṇa. One who knows what is Kṛṣṇa, "Kṛṣṇa is the origin. He's the original cause of all causes," sarva-kāraṇa-kāraṇam (Bs. 5.1), so he is brāhmaṇa. He is Vedantist. He knows everything. And if he acts like that, then what to speak...
That is advised here. Evaṁ jñātvā kṛtaṁ karma pūrvair api mumukṣubhiḥ. Evaṁ jñātvā. First of all it is the business of brāhmaṇa to understand. So if you cannot understand, then you do the business of kṣatriya. If you cannot do that, then do the business of a vaiśya. And if you cannot do that, then remain as a worker. Assist others. Assist the brāhmaṇa, the kṣatriya. So everyone will be engaged. And it is the duty of the government to see that nobody is unemployed. Then it will be devil's workshop. There will be so much movement, Communist movement, this movement, that movement, because everyone is not employed. The unemployment, devil's workshop, that is breeding so many isms and that... Otherwise, if anyone is engaged into work, his brain will not be a devil's workshop. He will work something.
