Ramayana 1.179

Then thus to King Bhagirath said Brahma, when, coming at the head Of all his bright celestial train, He saw those spirits freed from stain: "Well done! great Prince of men, well done! Thy kinsmen bliss and heaven have won. The sons of Sagar mighty-souled, Are with the Blest, as Gods, enrolled, Long as the Ocean's flood shall stand Upon the border of the land, So long shall Sagar's sons remain, And, godlike, rank in heaven retain. Ganga thine eldest child shall be, Called from thy name Bhagirathi; Named also--for her waters fell From heaven and flow through earth and hell-- Tripathaga, stream of the skies, Because three paths she glorifies. And, mighty King, 'tis given thee now To free thee and perform thy vow. No longer, happy Prince, delay Drink-offerings to thy kin to pay. For this the holiest Sagar sighed, But mourned the boon he sought denied. Then Ansuman, dear Prince! although No brighter name the world could show, Strove long the heavenly flood to gain To visit earth, but strove in vain. Nor was she by the sages' peer, Blest with all virtues, most austere, Thy sire Dilipa, hither brought, Though with fierce prayers the boon he sought. But thou, O King, earned success, And won high fame which God will bless. Through thee, O victor of thy foes, On earth this heavenly Ganga flows, And thou hast gained the meed divine That waits on virtue such as thine. Now in her ever holy wave Thyself, O best of heroes, lave: So shalt thou, pure from every sin, The blessed fruit of merit win. Now for thy kin who died of yore The meet libations duly pour. Above the heavens I now ascend: Depart, and bliss thy steps attend."
