SB 12.10.5
nibhrtoda-jhasa-vrato
vatapaye yatharnavah
kurv asya tapasah saksat
samsiddhim siddhi-do bhavan
Translation:
He is as calm as the waters of the ocean when the wind has ceased and the fish remain still. Therefore, my lord, since you bestow perfection on the performers of austerity, please award this sage the perfection that is obviously due him.
