Mbh 7.79.1a

“Sanjaya said, ‘Then lord Kesava, of eyes like lotus-petals, having entered the unrivalled mansion of Arjuna, touched water, and spread (for Arjuna) on the auspicious and even floor an excellent bed of Kusa blades that were of the hue of the lapis lazuli. And keeping excellent weapons around that bed, he adorned it duly with garlands of flowers and fried paddy, perfumes and other auspicious articles. And after Partha (also) had touched water, meek and submissive attendants brought the usual nightly sacrifice to the Three-eyed (Mahadeva). Then Partha, with a cheerful soul, having smeared Madhava with perfumes and adorned with floral garlands, presented unto Mahadeva the nightly offering.[131] Then Govinda, with a faint smile, addressed Partha, saying, “Blessed be thou, O Partha, lay thyself down, I leave thee.” Placing door-keepers then, and also sentinels well-armed, blessed Kesava, followed by (his charioteer) Daruka, repaired to his own tent. He then laid himself down on his white bed, and thought of diverse measures to be adopted. And the illustrious one (Kesava) of eyes like lotus petals, began for Partha’s sake, to think of various means that would dispel (Partha’s) grief and anxiety and enhance his prowess and splendour. Of soul wrapt in yoga, that Supreme Lord of all, viz., Vishnu of wide-spread fame, who always did what was agreeable to Jishnu, desirous of benefiting (Arjuna), lapsed into yoga, and meditation. There was none in the Pandava camp who slept that night. Wakefulness possessed every one, O monarch. And everybody (in the Pandava camp) thought of this, viz.,--“The high-souled wielder of Gandiva, burning with grief for the death of his son, hath suddenly vowed the slaughter of the Sindhus. How, indeed, will that slayer of hostile heroes, that son of Vasava, that mighty-armed warrior, accomplish his vow? The high-souled son of Pandu hath, indeed made a most difficult resolve. King Jayadratha is endued with mighty energy.
