Isayo Samuddakā
Isayo Samuddakā:Long ago,many virtuous seers lived in huts on the seashore.At that time there was a war between the gods and the Asuras.The seers considered the gods righteous but feared harm from the Asuras.They went,therefore,to Sambara,lord of the Asuras,and asked him for a pledge of safety; he refused,saying that the seers were followers of Sakka.The seers thereupon cursed him to suffer everlasting terror.It is said that that same night Sambara woke up thrice,seized with fright (S.i.227-8).
Buddhaghosa (SA.i.266) adds that as a result of this curse,Sambara’s mind became deranged and he came to be called Vepacitti (crazy-nerve).
