One time, Padma Purana says how when Bhakta Prahalad was preaching about Visnu bhakti and everything then, Hiranyakashipu got very angry and sent his soldiers to kill him. So first they tried…they struck him with a sword. But as soon as the weapon would hit Prahalad, it turned into a blue lotus, Neel Utpal. Blue lotus.
Another soldier came up with a spear and went to stab Prahalad in the heart, “kill him!” But as soon as it touched Prahalad, it turned into a blue lotus. Someone came up with his arrow, “Waargh”..more blue lotuses!
Whatever they would attack him with simply became blue lotuses. So he was covered by a big pile of blue lotuses. There were not able to harm him. Rather they were doing Pushpanjali!HH Jayapataka Swami Lecture Nrsimha Caturdasi, 2008 Sridham Mayapur
