A. Brahmä-vaivarta Puräna
In her last life Pütanä was Ratnamälä, the younger sister (daughter according to Garga Samhita) of Bali Mahäräja.
At the time when Bali was visited by Lord Vamanadeva she also witnessed His arrival.
As soon as Ratnamälä had set her eye on the Lord, she desired that He might become her son wishing to suckle Him out of maternal affection.
The Supreme Lord, feeling obliged to her father, His pure devotee, and understanding her heart, addressed Ratnamälä, promising that whatever desire she was cherishing at that moment would be fulfilled.
However, when Ratnamälä saw, how Lord Vamanadeva tricked her father and tied him up like a vagabond she became angry and bitter.
Looking at the Lord she thought maliciously: “If you become my son then not only will I feed you, I will kill you!”
According to the original benediction that Lord Vamanadeva had offered, Ratnamälä would have the opportunity to suckle Him as her child.
However, because her sentiments had now swung so violently to the opposite extreme, by exercise of His unlimited intelligence, Lord Vamanadeva ingeniously supplied the solution, by smoothly incorporating the suitable reactions to both diverse desires in a single event.
B. Garga Samhita
Seeing the form of Lord Vämana in Bali Mahäraja’s yajïa, Bali’s daughter Ratnamälä felt for the Lord (a mother’s) love for her son.
(She thought:) If I had a son like Him, then I would give that gloriously smiling son the milk from my breast to drink. In that way my heart would become happy.
“May your desire be fulfilled.”
In this way the Personality of Godhead, Lord Vämana, gave a blessing in his heart to the daughter of His great devotee Bali Mahäräja.
