Mbh 1.128.6

“Seeing these wonderful exhibitions of the might of Bhima, the powerful Duryodhana, the eldest son of Dhritarashtra, began to conceive hostility towards him. And the wicked and unrighteous Duryodhana, through ignorance and ambition, prepared himself for an act of sin. He thought, ‘There is no other individual who can compare with Bhima, the second son of Pandu, in point of prowess. I shall have to destroy him by artifice. Singly, Bhima dares a century of us to the combat. Therefore, when he shall sleep in the garden, I shall throw him into the current of the Ganga. Afterwards, confining his eldest brother Yudhishthira and his younger brother Arjuna, I shall reign sole king without molestation.’ Determined thus, the wicked Duryodhana was ever on the watch to find out an opportunity for injuring Bhima. And, O Bharata, at length at a beautiful place called Pramanakoti on the banks of the Ganga, he built a palace decorated with hangings of broad-cloth and other rich stuffs. And he built this palace for sporting in the water there, and filled it with all kinds of entertaining things and choice viands. Gay flags waved on the top of this mansion. The name of the house was ‘the water-sport house.’ Skilful cooks prepared various kinds of viands. When all was ready, the officers gave intimation to Duryodhana. Then the evil-minded prince said unto the Pandavas, ‘Let us all go to the banks of the Ganga graced with trees and crowned with flowers and sport there in the water.’ And upon Yudhishthira agreeing to this, the sons of Dhritarashtra, taking the Pandavas with them, mounted country-born elephants of great size and cars resembling towns, and left the metropolis.
