Buddhism or Advaita: why I follow Advaita

Buddhism is based on Hinduism & yoga beliefs. It’s easier to follow but differs in the philosophical conclusion: Buddhism does not seem to accept that there is an enlivening principle beyond body and mind. It concludes that a still body and mind produces ‘emptiness’ or ‘shunyata’ which was not acceptable to me. Advaita Vedanta provides me the most rational explanation that is in concurrence with my personal experience - the existence of a conscious principle!
