1. Serissaka. A Yakkha chieftain to be invoked in time of need by followers of the Buddha. D.iii.205.
2. Serissaka, Serísaka. A vimána in the Cátummahárájika world, which was occupied by Páyási during his life there. Gavampati, who used to go there for his siesta, met him and had a conversation with him, which he reported to the Buddha (D.ii.356f). The deva of the vimána was also called Serísaka, and is evidently to be identified with the Yakkha Serissaka.
Páyási was born in the Serísaka-vimána, because, though he gave generously, he was careless about the manner of giving. Vessavana therefore stationed him in a desert, devoid of shade or water, to protect travellers from the dangers which beset them at the hands of non-humans. He came across some merchants from Anga and Magadha who had lost their way while journeying to Sindhusovíra. He revealed to them his identity, and they offered to hold a festival in his honour when they reached safety. But he suggested that gifts be given in his name to a pious man, named Sambhava, who was in their company. Later Sambhava joined the Order and became an arahant (Vv.vii.10; VvA.331).
It is said (DA.iii.814; cf. ThagA.i.103) that the vimána was called Serísaka because there was, at its entrance, a large serísa-tree, which bore fruit once in fifty years. Gavampati had earlier occupied the vimána, when born as a devaputta. After his rebirth among humans, the vimána was empty till occupied by Páyási. But Gavampati sometimes visited it even after becoming an arahant.
