What is the name of the deified personification of the priest?

The correct answer is Brihaspati, who is revered as the deified personification of the priest in Hindu tradition. In Vedic texts, Brihaspati is closely associated with ritual and sacrifice, serving as the divine representative and guiding force for priests. He embodies the sacred knowledge and the role of the priest, emphasizing the importance of education, wisdom, and spiritual guidance.

Brahma, while a significant deity in Hinduism known as the creator god, does not specifically represent the priestly function. Vishnu is recognized as the preserver and protector within the Hindu trinity, linked to the maintenance of dharma (cosmic order), but he also does not embody the role of the priest. Shiva, the destroyer and transformer, holds a central place in Hindu worship but focuses more on destruction and renewal rather than the priestly duties associated with Brihaspati. Thus, Brihaspati uniquely encapsulates the essence of the priest within the pantheon of Hindu deities.
