Bhashya
न ह अप्सु प्रैति ।नेच्छति चेत् ।अप्सुमान् अम्मान्भ-वति फलम् ॥
In plain words
He does not come to harm in the waters. Should someone ask: if he does not wish it—he becomes possessed of waters. This is the fruit.
Close to the Sanskrit
Not indeed does he go to harm in the waters. If not, he desires. He becomes possessed of waters; the fruit.
