Sushen Vaidya is a character in the Ramayana, an ancient Indian epic. He was the royal physician of the monkey kingdom of Kishkindha, ruled by King Vali. When Vali was killed by Lord Rama, his brother Sugriva became the new king of Kishkindha, and Sushen Vaidya continued to serve as the royal physician.
Later, when Lord Rama was searching for his wife Sita, who had been kidnapped by the demon king Ravana, he encountered Hanuman, a monkey warrior and devotee of Lord Rama. Hanuman then introduced Lord Rama to Sugriva, and Sushen Vaidya played a key role in helping Lord Rama and Sugriva form an alliance to search for Sita.
During the search, Sushen Vaidya treated injured monkeys and bears, and also provided Lord Rama with valuable medical advice. He was highly respected for his knowledge and expertise in medicine, and his contributions were essential to the success of Lord Rama’s mission.
