Rebbi Jeremiah, Rebbi Abba bar Mamal in the name of Rav: If a scroll started burning at one side one puts water on the other side¹²⁰This is indirect causation of extinguishing which only is rabbinically forbidden and is tolerated in this case.; if it was extinguished it was extinguished. If the fire burned on both sides one spreads it out and reads in it; if it was extinguished it was extinguished. ¹²¹Babli 120a bottom. If a toga started burning at one side one puts water on the other side; if it was extinguished it was extinguished. If the fire burned on both sides one takes it and wraps oneself in it; if it was extinguished it was extinguished.
