TIHAR , is one of the great celebrations in the Hindu calendar, is a five-day autumn festival generally known as the festival of lights. Regardless of regional and denominational differences, TIHAR is a period of gift-giving, storytelling, and recognition of the relationships humans have with all things.
In narratives, dogs are associated with death which is why Sarama’s children, the Sarameya, are the companions of Yama, god of death. They are associated not with civilization but with the wilderness which is why they are associated with mendicants, like Dattatreya. The dog is the mount of Bhairava, the fearsome form of Shiva. A dog is considered so inauspicious that in the Mahabharata, Yudhishtira is not allowed to enter heaven with the dog.
Some would argue that dogs rummage through garbage which is why they are unclean, which is why they are not allowed to come near temples. But these rational explanations do not provide a satisfactory answer. Literal interpretations are convenient but not correct. Logically speaking, a dog should be the symbol of devotion in Hinduism; yet Hindus worship Hanuman, the monkey-god, as the perfect devotee. Mythology must never be taken literally; mythology is symbolic. Mythic stories and symbols are a code, a medium through which the ancestors are communicating profound messages. When the dog is considered inauspicious, it means the dog represents a thought that is inauspicious. What is this inauspicious thought?
In the Bhagavata Purana is the story of Bharata who is a hermit in the forest. He gives up everything but slowly gets attached to a deer. As a result, he is unable to attain moksha. He is reborn as a deer, trapped once more in the cycle of rebirth. Attachment entraps: this is a key maxim in Hindu philosophy.
