KṢUPA I A Prajāpati. There is a story about the birth of this Prajāpati in
[Mahābhārata] . Once Brahmā wished to perform a sacrifice. But he could not get suitable priest as the performer of the sacrifice. So Brahmā decided to create a befitting person as Ṛtvik (the priest who does the rituals of the sacrifice) and he got pregnant in his head. After a thousand years he sneezed and a Prajāpati came out of the head of Brahmā. That Prajāpati was Kṣupa. He made Kṣupa his Ṛtvik.
[Mahābhārata, Śānti Parva, Chapter 122] . Rudra Bhagavān made him Prajāpati (the Lord of all subjects).
KṢUPA II A King who was the son of Prasandhi, and the grandson of Vaivasvata Manu. He was the father of Ikṣvāku. In
[Mahābhārata, Sabhā Parva, Chapter 8] , it is mentioned that Kṣupa stayed in the Palace of Yama after his death. In
[Mahābhārata, Śānti Parva, Chapter 166] it is stated that this King had received a sword directly from Vaivasvata Manu. Kṣupa was not in the habit of eating flesh.
