As Regan's behavior becomes increasingly erratic and disturbing, Chris becomes concerned and seeks the help of a priest, Father Damien Karras (played by Jason Miller). Father Karras is a young priest who is struggling with his faith, and he is initially hesitant to get involved. However, he eventually teams up with a veteran priest, Father Lankester Merrin (played by Max von Sydow), who has experience with demonic possession.
The Hindi dubbed version of The Exorcist, titled "The Exorcist - 1973 - Hindi Dubbed 48...", is a version of the film that has been translated into Hindi. The dubbed version was likely created for audiences in India and other Hindi-speaking countries. The quality of the dubbed version may vary, but it is likely to be of lower quality than the original English-language version.
As the possession worsens, Father Karras and Father Merrin attempt to perform an exorcism on Regan. The exorcism is a series of rituals and prayers that are designed to drive the demon out of Regan's body. However, the exorcism is a difficult and painful process, and it takes a toll on both Father Karras and Father Merrin.
