Vaishnava Samhita. Shri Kumbhaadasa Charitam. Vol III Book VII Chp 7 Shlokas 2 - 5

येषां भक्तवरिष्ठानां कृष्णनाम परं धनम् |

दरिद्राश्चापि ते भक्ता न पश्यन्ति धनोन्मदान् ||

कामिनीकाञ्चनासक्तिः कृष्णभक्तिविनाशिनी |

यदृच्छलाभसंतुष्टः स्वदारनिरतो भवेत् ||

दारिद्रेनैव जीवन्तो भजन्तो नन्दनन्दनम् |

यत्सुखं प्राप्नुयुर्भक्ताः न तत्सर्वे धनोन्मदाः ||

ययाकया च वृत्यैव लोके जीवितमाचरन् |

विश्वासेन दृढेनैव भजेत्तं पुरुषोत्तमम् ||

The great bhaktas have Krishna bhakti as their only asset. Even when they are actually very poor, they do not care for the rish people who are proud of their wealth.The desire for gold and lust for women destroy the bhakti towards Shri Krishna. Hence one should remain contented with his lot and should possess unaltering love for his wife. The comfort and happiness that the bhaktas who lead a simple life nurturing devotion to Shri Nandakumara, enjoy, are not attained by any wealthy man. Hence, we should earn our livelihood, taking up some occupation and spend our time pondering on the Purushottama with firm belief.
