He consulted the Jain monk Jiva-siddhi to decide an auspicious time for beginning the march. Jiva-siddhi, a spy of Chanakya, told him that he could start immediately. Jiva-siddhi also convinced him that Rakshasa was responsible for his father's death, but Bhagurayana persuaded him not to harm Rakshasa. Shortly after, Chanakya's spy Siddharthaka pretended to get caught with a fake letter addressed to Chandragupta by Rakshasa. Wearing the jewels given by Rakshasa, he pretended to be an agent of Rakshasa. The letter, sealed with Rakshasa's signet-ring, informed Chandragupta that Rakshasa only wished to replace Chanakya as the prime minister. It also stated that five of Malayaketu's allies were willing to defect to Chandragupta in return for land and wealth. An angry Malayaketu summoned Rakshasa, who arrived wearing Parvata's jewels that Chanakya's agent had sold him. When Malayaketu saw Rakshasa wearing his father's jewels, he was convinced that there was indeed a treacherous plan against him. He executed his five allies in a brutal manner. The rest of Malayaketu's allies deserted him, disgusted at his treatment of the five slayed allies. Rakshasa managed to escape, tracked by Chanakya's spies. One of Chanakya's spies, disguised as a friend of Chandana-dasa, got in touch with him. He told Rakshasa that Chandana-dasa was about to be executed for refusing to divulge the location of Rakshasa's family. On hearing this, Rakshasa rushed to Pataliputra to surrender and save the life of his loyal friend Chandana-dasa. When he reached Pataliputra, Chanakya, pleased with his loyalty to Chandana-dasa, offered him clemency. Rakshasa pledged allegiance to Chandragupta and agreed to be his prime minister, in return for release of Chandana-dasa and a pardon for Malayaketu. Chanakya then bound his top knot, having achieved his objective, and retired. Chanakya is regarded as a great thinker and diplomat in India. Many Indian nationalists regard him as one of the earliest people who envisioned a united India spanning the entire subcontinent.
