unto the demons

O Lord Brahma, born from the lotus flower

just as.

The Personality of Godhead replied: My dear Lord Brahma, O great lord born from the lotus flower, just as it is dangerous to feed milk to a snake, so it is dangerous to give benedictions to demons, who are by nature ferocious and jealous. I warn you not to give such benedictions to any demon again.
