In hindu texts, the same person typically has multiple names.
The Vishnu Sahastranamam is the biggest example.
Shiva has many names such as Rudra, Neelkanth, Manjunath, etc.
Mahadevi has many names including Parvati, Durga, Kaali, etc.
Why are there so many names of the same person? Is it specific to the gods/Kings/revered people, or do most people in the texts have multiple names?
Aside: Please add proper tags to this question :)
