Mbh 12.359.1

"'Bhishma said, "Upon the expiry of the period of full fifteen days, the Naga chief (Padmanabha), having finished his task of dragging the car of Surya and obtained the latter's permission, came back to his own house. Beholding him come back, his spouse approached him quickly for washing his feet and dutifully discharging other tasks of a similar nature. Having gone through these tasks, she took her seat by his side. The Naga then, refreshed from fatigue, addressed his dutiful and chaste wife, saying, 'I hope, my dear wife, that during my absence thou hast not been unmindful of worshipping the deities and guests agreeably to the instructions I gave thee, and according to the ordinances laid down in the scriptures. I hope, without yielding to that uncleansed understanding which is natural to persons of thy sex, thou hast, during my absence from home, been firm in the observance of the duties of hospitality. I trust that thou hast not transcended the barriers of duty and righteousness.'
