Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 34

Sanskrit:

नानाकर्मवितानेन प्रजा बह्वी: सिसृक्षत: ।नात्मावसीदत्यस्मिंस्ते वर्षीयान्मदनुग्रह: ॥ ३४ ॥

ITRANS:

nānā-karma-vitānenaprajā bahvīḥ sisṛkṣataḥnātmāvasīdaty asmiṁs tevarṣīyān mad-anugrahaḥ

Translation:

Since you have desired to increase the population innumerably and expand your varieties of service, you shall never be deprived in this matter because My causeless mercy upon you will always increase for all time.

Purport:

A pure devotee of the Lord, being cognizant of the facts of the particular time, object and circumstances, always desires to expand the number of devotees of the Lord in various ways. Such expansions of transcendental service may appear to be material to the materialist, but factually they are expansions of the causeless mercy of the Lord towards the devotee. Plans for such activities may appear to be material activities, but they are different in potency, being engaged in the satisfaction of the transcendental senses of the Supreme.
