While Lord Kṛṣṇa was speaking to Sudāmā Vipra, He ate one morsel of chipped rice from his bundle, and when He attempted to eat a second morsel, Rukmiṇīdevī, the goddess of fortune herself, checked the Lord by catching hold of His hand. After touching the hand of Kṛṣṇa, Rukmiṇī said, "My dear Lord, this one morsel of chipped rice is sufficient to cause him who offered it to become very opulent in this life and to continue his opulence in the next life. My Lord, You are so kind to Your devotee that even this one morsel of chipped rice pleases You very greatly, and Your pleasure assures the devotee opulence in both this life and the next." This indicates that when food is offered to Lord Kṛṣṇa with love and devotion and He is pleased and accepts it from the devotee, Rukmiṇīdevī, the goddess of fortune, becomes so greatly obliged to the devotee that she has to go personally to the devotee's home to turn it into the most opulent home in the world. If one feeds Nārāyaṇa sumptuously, the goddess of fortune, Lakṣmī, automatically becomes a guest in one's house, which means that one's home becomes opulent. The learned brāhmaṇa Sudāmā passed that night at the house of Lord Kṛṣṇa, and while there he felt as if he were living on a Vaikuṇṭha planet. Actually he was living in Vaikuṇṭha, because wherever Lord Kṛṣṇa, the original Nārāyaṇa, and Rukmiṇīdevī, the goddess of fortune, live is not different from the spiritual planets, Vaikuṇṭhaloka.
The learned brāhmaṇa Sudāmā did not appear to have received anything substantial from Lord Kṛṣṇa while at His palace, yet he did not ask anything from the Lord. The next morning he started for his home, thinking always about his reception by Kṛṣṇa, and thus he merged in transcendental bliss. All the way home he simply remembered the dealings of Lord Kṛṣṇa, and he felt very happy to have seen the Lord.
