Srimad Bhagvata Mahapurana: Book 10: Chapter 81: Verses 1-14
The story of parched rice brought as a Present (for Sri Krsna) by Sudama
Sri Suka began again : ( Pariksit!) Bhagavan Sri Krsna knows the mind of all beings. He is devoted to Brahmanas (always takes care to relieve their suffering) and is the sole refuge of saints. Thus heartily talking alongwith that honourable Brahmana, He now smilingly spoke to His dear comrade in a jesting mood looking at him with eyes full of affection. The glorious Lord said : "0 friend, what present have you brought for Me from your house? I consider as great even a small present offered by the devotee with real love; but a lot of things offered without devotion do not bring Me pleasure. Whosoever offers to Me with love a leaf, a flower, a fruit or even water, I accept and heartily enjoy that offering of love by that man of purified intellect." Pariksit, though encouraged by the Lord in this way, the Brahmana, feeling shy, did not present the handful of beaten rice to the Lord of Laksmi (the goddess of wealth) Himself. He (simply) hung his head. But the Lord, who sees the mind of all beings, knew the cause of his visit. He said to Himself, "This Brahmana is a great friend of Mine; he never sought wealth from Me before. He approached Me now, at the entreaty of his devoted wife, whom he is naturally anxious to please. I shall bestow on him a fortune which is difficult of attainment even by the immortals." Reflecting thus, the Lord snatched from under the covering of the Brahmana the beaten rice tied in a rag and said "Dear comrade, what is this? Here you have brought Me something which I like most.
