In plain words
For such discerning knowledge, purity of citta is needed. To a man with purity of citta all knowledge comes of its own accord. To foster this purity of citta, we must regard love of God and fear of sin as the chief things. You may have a doubt: at what time, and in what circumstances, should we make use of fear of sin and love of God? Śaṅkara gave a fine answer to this. ‘Yogaratovā, bhogaratovā, saṅgaratovā, saṅgavihīnaḥ yasya ramate cittaṃ nandati nandati nandatyeva,’ he said. Yogaratovā, saṅgaratovā: in union and in separation, in poverty and in prosperity, in dealings and in farming, in trade and on the battlefield, why name only one, at all times and in all states we must follow these two, fear of sin and love of God, as the chief thing. Only on the strength of these two can man walk the right path.
When everyone in society carries out the Dharma enjoined on him properly, corruption comes to an end
When a merchant acts with fear of sin and love of God and does his daily work, there is no disturbance or unrest of any kind in society. Unlawful dealing, unlawful hoarding, the black market, smuggling and such wicked deeds can find no room in trade. When the merchant and his partners, doctors, lawyers, judges, government officers, politicians and teachers properly keep to the Dharma enjoined on them, corruption vanishes. If corruption is to be rooted out, each one has to carry out his own share, his own duty, properly. Carrying out one's duty in this way is what is called value. To believe in your work as the Dharma enjoined on you, and to practise it: that is the main thing, in business.
