In the Padma Purana,
Who would desire to eat food that is full of the saliva of another man's mouth and has been touched by another man's body? || 126 ||
Vibhishana, who was dear to Ravana, heard this with pleasure. Vibhishana, who was a knower of policy and always a leader among the councilors, said this: || 127 ||
O God! Since this is the way things are, a king who knows policy must always tell a lie, even if it is a small one. || 128 ||
Perhaps, by accepting, she will be pleased and, having gained confidence, will tell some way to take the city. || 129 ||
Then, following Vibhishana's words, Ravana, who was a follower of deceit, said to the messenger: O Bhadra! What you have said is right. || 130 ||
That poor woman's life is stuck in me, and she is in great distress. She is worthy of being protected by me. Indeed, generous people are compassionate. || 131 ||
Therefore, go and bring her back, even if it costs you your life. It is heard in the world that it is Dharma to protect living beings. || 132 ||
Having said this, Ravana sent the messenger, who went and brought back Uparambha in a moment. Ravana honored her greatly upon her arrival. || 133 ||
Then, when Uparambha, who was under the sway of Kama, reached Ravana, Ravana said: O Devi! My intense desire is to enjoy myself in the city of Durlagha. || 134 ||
Tell me, what pleasure is there in this forest? And what is the cause of Kama? O Devi! Do something so that I can enjoy myself with you in the city. || 135 ||
Women are naturally easily deceived, so Uparambha did not understand Ravana's cunning. In short, she, being afflicted by Kama, gave him the knowledge called Ashalika, which stood as a rampart, and various weapons, which were protected by Vyantara Devas, with great respect. || 136-137 ||
As soon as she received the knowledge, that illusory rampart disappeared, and in its absence, the city remained surrounded only by its natural rampart. || 138 ||
Ravana, with a large army, reached near the city. Hearing the noise of the city, Nalakuvara became agitated. || 139 ||
