SB 6.18.70
ekah sankalpitah putrah
sapta saptabhavan katham
yadi te viditam putra
satyam kathaya ma mrsa
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
I prayed for only one son, but now I see that there are forty-nine. How has this happened? My dear son Indra, if you know, please tell me the truth. Do not try to speak lies.
