The first recorded instance of an American being converted to Buddhism on American soil occurred at the 1893 exposition on world religions and the convert had been a Jew named Charles Strauss. According to the Ten Commandments and classical Jewish law, known as Halacha, it is forbidden for any Jew to worship any deity other than the way God is worshipped in Judaism – specifically by bowing, offering incense, sacrifices and/or poured libations. The use of the term "spirituality" has changed throughout the ages. In modern times, spirituality is often separated from Abrahamic religions, and connotes a blend of humanistic psychology with mystical and esoteric traditions and eastern religions aimed at personal well-being and personal development. The term "meditation" can refer to the state itself, as well as to practices or techniques employed to cultivate the state.
