Relates the story of how, when Sakka led his forces into battle, he told them that should any panic arise in their heart, they should look at the crest of his banner and their fears would immediately vanish. Or they should look at the banners of Pajápatí or Varuna or Isána. Similarly should any fear arise in the mind of a monk he should recall to mind the excellences of the Buddha, or the Dhamma, or the Sangha, and peace would come to him (S.i.218f).
This sutta is also included among the Parittas and is called the Dhajagga Paritta (E.g., Mil.150).
It is said that once a sámanera, helping to plaster the Díghavápi cetiya, fell from the top. His colleagues shouted to him to recall the Dhajagga Paritta. He did so, and was miraculously saved. SA.i.262f.
