Here the two modes of nature is explained, kāma and lobha, er, rajas-tamas. So if we are entangled with rajas-tamas, then our perpetual desire for lusty sense enjoyment and greediness will not stop. It will drag me more and more, more and more, and entangle me. But sthitaṁ sattve prasīdati. But if we give up these two qualities, the remainder quality means goodness, that sattve, you will give . . . you will get, at least, peace of mind. Sthitaṁ sattve prasīdati. Evaṁ prasanna-manasaḥ. When you are in, in the platform of satisfaction, sattva-guṇa . . . just like the brahminical qualification, they are satisfied with anything. A brāhmaṇa is not supposed to improve his economic condition. He's not interested. He's simply satisfied, "By the grace of God, whatever I have got, that is sufficient." God is supplying everyone, even birds and beasts and cats and dogs. Eko yo bahūnāṁ vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13). He is giving food to everyone. So sattva-guṇa means to remain satisfied whatever is obtained by . . . from God, by His free will. That's all. They are not after economic development.
So Vaiṣṇava, being inherently a brāhmaṇa, he should be satisfied, "Whatever Kṛṣṇa has given, that's all right. My business is how to make advance in Kṛṣṇa consciousness." Tasyaiva hetoḥ prayateta kovidaḥ. That is the Vaiṣṇava's business, that simply how to make perfection of life in Kṛṣṇa consciousness. That is Vaiṣṇava's demand; not for any other improvement, economic development or this improvement. No. Because economic . . . it is . . . it is a false idea that one will be satisfied or be happy simply by economic development. No, that is not possible, practically. In your country, America, there is immense economic development, but you could not get any happiness. That is not possible. Happiness will be possible when, first of all, you are situated in the brahminical position, sattva-guṇa; and to come to that brahminical position, you have to give up the activities of rajas-tamo-guṇa. The rajas-tamo-guṇa is that illicit sex, meat-eating, intoxication and gambling. That's all. So if you voluntarily give up, and be situated in the sattva-guṇa, then you'll be happy. Evaṁ prasanna-manasaḥ.
And that happiness can be obtained, as it is stated here, bhakti, by devotional service.
