The Lord never gives condemned benedictions
The demigods, to keep their prestigious positions, bestow upon their worshipers whatever benedictions the worshipers want. For example, once it was found that an asura took a benediction from Lord Siva by which the asura would be able to kill someone simply by placing his hands on that person’s head. Such benedictions are possible to receive from the demigods. If one worships the Supreme Personality of Godhead, however, the Lord will never offer him such condemned benedictions.
