Which came first, the coffee or the yoga?

The earliest credible evidence of either coffee drinking or knowledge of the coffee tree appears in the middle of the fifteenth century, in the Sufi monasteries in Yemen. It was here in Arabia that coffee beans were first roasted and brewed, in a similar way to how it is now prepared.

The term "yoga" first appears in the Hindu scripture Katha Upanishad (400 BCE) where it is defined as the steady control of the senses, which leads to the supreme state.
