Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 15

Sanskrit:

यात्रामात्रं त्वहरहर्दैवादुपनमत्युत ।नाधिकं तावता तुष्ट: क्रिया चक्रे यथोचिता: ॥ १५ ॥

ITRANS:

yātrā-mātraṁ tv ahar ahardaivād upanamaty utanādhikaṁ tāvatā tuṣṭaḥkriyā cakre yathocitāḥ

Translation:

By the will of Providence he obtained each day just what he needed for his maintenance, and no more. Satisfied with this much, he properly executed his religious duties.

Purport:

An ideal Vaiṣṇava brāhmaṇa, even if encumbered by the ties of family life, should work only as hard as required to meet his obligations. Without being unnecessarily agitated for material advancement, he should devote the best part of his time and assets to his higher duties in the Supreme Lord’s service. If a householder can succeed in this program despite the unavoidable difficulties of this degraded age, he can expect Lord Kṛṣṇa’s personal attention, as will be seen in the case of Śrutadeva, the perfect brāhmaṇa of Mithilā.
