The Lazy Yogi writes at Reality Sandwich:
If we desire enlightenment only for ourselves, then living in society will seem like a hindrance. Everything will appear as an obstacle keeping you from your spiritual lifestyle and practices. You will feel a drive to escape, perhaps to nature or to an ashram. But wherever you go, your mind comes with you.
A key component is Motivation. If you seek peace and enlightenment only for yourself, then the world will continually get in the way. However, the Tibetan Buddhists have a different thought in mind. They aspire to enlightenment for the benefit of all Beings.
If we want to live in a beautiful and awakened world of majesty and harmony, then all change must start with ourselves. But we cannot wait until we are perfect before extending compassion to the world. Therefore even as we walk the path, we must also create the space to allow others to do so as well.
