Acharya Prashant explains that the Indian custom of adding 'Ji' to a name has a deep spiritual foundation, distinguishing it from titles like 'Mister'. He notes that while a name refers to the physical body and a surname refers to the mind and history, these two alone do not represent the entirety of a person. The term 'Ji' is derived from the Sanskrit word 'Shri', which signifies abundance, auspiciousness, beauty, and the true self or Atman. By adding 'Ji', one is reminded that they are much more than just a body and a mind. He contrasts the Vedantic approach with that of the Buddha. While the Buddha might suggest that one is beyond all names and forms, Vedanta acknowledges the body and mind as facts but encourages identification with something higher, the 'Shri'. This serves as a reminder that the truth of a person exists before their physical identity and remains after it ceases. Although 'Ji' is often used today as a hollow mark of respect or a simple affirmative in conversation, its original purpose was to point toward the ultimate truth and the real essence of an individual.
