In Hindu mythology, there are several characters believed to be immortal. One of them is Ashwatthama, son of Dronacharya, who was cursed to roam the earth for 3,000 years in extreme pain. Another is Lord Hanuman, one of the seven ‘Chiranjeevis’, blessed with immortality by Lord Rama. Similarly, Vibhishan, Parshuram, and Mahabali are also considered to be immortal due to various boons and blessings. These characters are revered and celebrated in Hindu culture, with their stories and legends being passed down for generations.
