Mbh 12.334.1b

The Gandharvas and the Rishis also and others that dwelt in that mountain being rent in twain and Suka passing through it. Indeed, O Bharata, a loud noise was heard everywhere at that moment, consisting of the words--Excellent, Excellent!--He was adored by the Gandharvas and the Rishis, by crowds of Yakshas and Rakshasas, and all tribes of the Vidyadharas. The entire firmament became strewn with celestial flowers showered from heaven at that moment when Suka thus pierced through that impenetrable barrier, O monarch! The righteous-souled Suka then beheld from a high region the celestial stream Mandakini of great beauty, running below through a region adorned by many flowering groves and woods. In these waters many beautiful Apsaras were sporting. Beholding Suka who was bodiless, those unclad aerial beings felt shame. Learning that Suka had undertaken his great journey, his sire Vyasa, filled with affection, followed him behind along the same aerial path. Meanwhile Suka, proceeding through that region of the firmament that is above the region of the wind displayed his Yoga-prowess and identified himself with Brahma.[1788] Adopting the subtile path of high Yoga, Vyasa of austere penances, reached within the twinkling of the eye that spot whence Suka first undertook his journey. Proceeding along the same way, Vyasa beheld the mountain summit rent in twain and through which Suka has passed. Encountering the Island-born ascetic, the Rishis began to represent to him the achievements of his son. Vyasa, however, began to indulge in lamentations, loudly calling upon his son by name and causing the three worlds to resound with the noise he made. Meanwhile, the righteous-souled Suka, who had entered the elements, had become their soul and acquired omnipresence, answered his sire by uttering the monosyllable Bho in the form of an echo. At this, the entire universe of mobile and immobile creatures, uttering the monosyllable Bho, echoed the answer of Suka.
