When we practice, initially, as a basis we control ourselves, stopping the bad actions which hurt others as much as we can. This is defensive. After that, when we develop certain qualifications, then as an active goal we should help others. In the first stage, sometimes we need isolation while pursuing our own inner development; however, after you have some confidence, some strength, you must remain with, contact, and serve society in any field -- health, education, politics, or whatever.

There are people who call themselves religious-minded, trying to show this by dressing in a peculiar manner, maintaining a peculiar way of life, and isolating themselves from the rest of society. That is wrong. A scripture of mind-purification (mind-training) says, "Transform your inner viewpoint, but leave your external appearance as it is." This is important. Because the very purpose of practicing the Great Vehicle is service for others, you should not isolate yourselves from society. In order to serve, in order to help, you must remain in society.
