Even if a person such as Satan exists, he is no more than a special jiva (living entity) under the control of God, and has no power to do anything that is opposed to God’s will. However, in my opinion, it is not possible for such a monstrous living entity to exist. No activity can take place that is contrary to the will of Isvara, nor is any living entity independent of the Lord.
Yesterday was Makhara-sankranti, the descending of the Ganges River. All Indians, even those living very far away from Ganges, will somehow go there to take bath.

On this day all the bathing ghats are full with hundreds of thousands of people.

Kṛṣṇa was bound simply by that.

Please give me money.” Lord Siva told him, “Go to Vrndavana and meet with Srila Sanatana Gosvami. You can ask him to give you some wealth for your daughter’s marriage.” The brahmana went to Vrndavana, by foot, and there he asked the villagers there for the whereabouts of a person named Sanatana Gosvami. As they all knew him, they pointed out his residence.
