Mbh 3.24.2a

“Vaisampayana continued, “Then the virtuous son of Pandu, accompanied by numerous Brahmanas, all went to the sacred lake called Dwaitavana. And Yudhishthira was surrounded by numerous Brahmanas some of whom sacrificed with fire and some without it and some of whom, devoted to the study of the Vedas, lived upon alms or were of the class called Vanaprasthas. And the king was also surrounded by hundreds of Mahatmas crowned with ascetic success and of rigid vows. And those bulls of the Bharata race, the sons of Pandu setting out with those numerous Brahmanas, entered the sacred and delightful woods of Dwaita. And the king saw that mighty forest covered on the close of summer with Salas, and palms, and mangoes, and Madhukas, and Nipas and Kadamvas and Sarjjas and Arjunas, and Karnikars, many of them covered with flowers. And flocks of peacocks and Datyuhas and Chakoras and Varhins and Kokilas, seated on the tops of the tallest trees of that forest were pouring forth their mellifluous notes. And the king also saw in that forest mighty herds of gigantic elephants huge as the hills, with temporal juice trickling down in the season of rut, accompanied by herds of she-elephants. And approaching the beautiful Bhogavati (Saraswati), the king saw many ascetics crowned with success in the habitations in that forest, and virtuous men of sanctified souls clad in barks of trees and bearing matted locks on their heads. And descending from their cars, the king that foremost of virtuous men with his brothers and followers entered that forest like Indra of immeasurable energy entering heaven. And crowds of Charanas and Siddhas, desirous of beholding the monarch devoted to truth, came towards him. And the dwellers of that forest stood surrounding that lion among king possessed of great intelligence.
