This is a quotation from Śrīmad-Bhāgavatam (SB 2.2.5). In this verse, Śukadeva Gosvāmī advises Mahārāja Parīkṣit that a devotee should be independent in all circumstances. The body can be maintained with no problem if one follows the instructions given in this verse. To maintain the body, we require shelter, food, water and clothing, and all these necessities can be obtained without approaching puffed-up rich men. One can collect old garments that have been thrown out, one can eat fruits offered by the trees, one can drink water from the rivers, and one can live within the caves of mountains. By nature’s arrangements, shelter, clothing and food are supplied to the devotee who is completely surrendered to the Supreme Personality of Godhead. Such a devotee does not need a puffed-up materialistic person to maintain him. In other words, devotional service can be discharged in any condition. This is the version of Śrīmad-Bhāgavatam (SB 1.2.6):
- sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje
- ahaituky apratihatā yayātmā suprasīdati
“The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be unmotivated and uninterrupted in order to completely satisfy the self.” This verse explains that devotional service cannot be checked by any material condition.
