The variation, "Wherever you go, there you are" resonates (Jon Kabat-Zinn). But the thought behind the phrase may be better known to you as living in the moment, or mindfulness.
The English term mindfulness has been in use for centuries, long predating its use in the Buddhist context. The OED defines it as "The state or quality of being mindful; attention; regard", with obsolete meanings of "memory" and "intention, purpose". This word was first recorded as myndfulness in 1530.
