If we talk about his areas of core competency, then Vedic astrology and Palmistry happens to be two of them. He has come a long way in these fields and aced these arts.
Also, Hindi and Bhojpuri are the languages he is comfortable in and he is very often seen offering advisories in these two languages only.
