"Bhishma said. 'Then, O mighty-armed king, Sikhandin's mother represented unto her lord the truth about her daughter, Sikhandin. And she said, 'Childless, O great king, as I was, from fear of my co-wives, when Sikhandini, my daughter, was born, I represented unto you that it was a son! For thy love of me, thou also hadst corroborated it, and, O bull among kings, thou hadst performed all the rites prescribed for a son in respect of this daughter of mine! Thou then didst marry her, O king, to the daughter of the king of the Dasarnakas. I also approved of this act, remembering the words of the (great) god! Indeed, I did not prevent it, remembering the words of Siva,--Born a daughter, she will become a son!' Hearing all this, Drupada, otherwise called Yajnasena, informed all his counsellors of these facts. And, O monarch, the king then took counsel with ministers for the proper protection of his subjects (from the would-be invader). Although he had himself deceived the king of the Dasarnakas, yet giving it out that the alliance he had made was proper, he began to settle his plans with undivided attention. King Drupada's city was, O Bharata, naturally well-protected. Yet at the advent of danger, O monarch, they began to protect it all the more carefully and fortify it (with defensive works). The king, however, with his queen, was greatly afflicted, thinking of how a war might not take place with his brother. Reflecting on this, he began to pay his adorations to the gods.
