"I am spiritually inclined and have always known little about our mythology. But when I was prepping for '3 Dev'. I studied mythology in detail and was deeply inspired," Karan said in a statement.
The "Alone" star's character in "3 Dev" is said to be inspired by lord Vishnu. Karan will be seen playing a modern day Vishnu in the film.
He is busy going through verses from the Hindu holy book Gita and other mythological books to seek inspiration for his role.
"There are so many simple lessons one can learn from them and actually apply them practically in one's daily lives," Karan added.
Directed by Ankoosh Bhatt, "3 Dev" also stars Ravi Dubey, Kunaal Roy Kapur and Kay Kay Menon.
