Acharya Prashant explains that the suffix 'ji' is not merely a formal title like 'Mister' or 'Miss' but has a profound spiritual foundation rooted in Sanskrit. He notes that while names refer to the physical body and surnames refer to the mind and ancestral history, 'ji' is derived from the Sanskrit word 'Shri'. Shri represents abundance, auspiciousness, and the true self or Atman. By adding 'ji' to a name, one is reminded that they are much more than just a body and a mind; it points toward the eternal truth that exists before and after the physical form.
