Mahabharata Drona Parva Chapter 143:2

Mahabharata Drona Parva (Jayadratha-Vadha Parva) Chapter 143:2 I have now told thee, O king, what thou hadst asked me. Indeed, the Satwata hero is incapable of being vanquished in battle by even the foremost of men. The Vrishni heroes are all of sure aim in battle, and are conversant with all modes of warfare. They are vanquishers of the very gods, the Danavas and the Gandharvas. They are never confounded. They always fight, relying upon their own energy. They are never dependent on others. None, O lord, are seen in this world to be equal to the Vrishni's. None, O bull of Bharata's race, have been, are, or will be equal in might to the Vrishni's. They never show disrespect to their kinsmen. They are always obedient to the commands of those that are reverend in years. The very gods and Asuras and Gandharvas, the Yakshas, the Uragas and the Rakshasas cannot vanquish the Vrishni heroes, what need be said of men, therefore, in battle? They never covet also the possessions of those that ever render them aid on any occasion of distress. Devoted to the Brahmanas and truthful in speech, they never display any pride although they are wealthy. The Vrishnis regard even the strong as weak and rescue them from distress. Always devoted to the gods, the Vrishnis are self-restrained, charitable, and free from pride. It is for this that the prowess of the Vrishnis is never baffled. A person may remove the mountains of Meru or swim across the ocean but cannot defeat the Vrishnis. I have told thee everything about which thou hadst thy doubts. All this, however, O king of the Kurus, that is happening is due to thy evil policy, O best of men!
