Peace always begins within each of us. Our ability to create in the world depends on our ability, first, to work to create peace in our own lives. It's much easier to advocate peace on Earth than it is to be able to bring peace your own home. Or your own heart.
Serious spiritual practice is more than serene walks in the woods, lit candles and incense. You have to be committed. Your have to be willing to enter into your own darkness and transcend it.
