Hanuman ji is ansheek of Lord Shiv and since Shiv is known as the destructor of evil, Hanumanji is known as the destructor of troubles (sankat mochan).
In Hindu belief systems, Hanuman is often regarded as an “ansh” or partial incarnation of Lord Shiv. He is considered the 11th Rudra avatar of Lord Shiv, who is one of the principal deities in Hinduism. This belief attributes some of Hanuman’s divine qualities and characteristics to Lord Shiv.
While Hanuman is considered an ansheek or partial incarnation of Lord Shiv, he is primarily associated with his unwavering devotion to Lord Ram, an avatar of Lord Vishnu. Hanuman’s role in the Ramayan epic and his devotion to Lord Ram are central aspects of his story and significance in Hindu mythology.
It’s important to note that Hindu beliefs and traditions can vary, and interpretations of Hanuman’s divine nature may differ among different communities and traditions within Hinduism. In many traditions, Hanuman is revered for his devotion and strength, regardless of his divine origins as an ansheek or partial incarnation of Lord Shiv.
