Emptiness is usually connected with the impermanence of phenomena (anicca) and with not-self (anatta) In other words there is no fixed 'self', its always constantly changing and therefore is empty of anything permanent and this is also true of phenomena in general. We can also begin to understand emptiness through meditation, when our mind starts to become settled and still. These words from the section "Studying and Experiencing" in Ajahn Chah's "A still Forest Pool" might be helpful: http://www.what-buddha-taught.net/Bo...dhas Teachings
