If you believe free speech is for you but not your political opponents, you're illiberal.

The purpose of meditation is to create focus. It is about focusing your attention on your experience. The reason for focus: it allows you to be here now. Your only reality is This Moment, right here, right now. Peace is found in such awareness.
