Spiritual Practices -- The Dalai Lama

"However, if you think seriously about the true meaning of spiritual practices, it has to do with the development and training of your mental state, attitudes, and psychological and emotional state and well-being. You should not confine your understanding of spiritual practice to terms of some physical activities or verbal activities, like doing recitations of prayers and chanting. If your understanding of spiritual practice is limited to only these activities, then, of course, you will need a specific time, a separate allotted time to do your practice--because you can't go around doing your daily chores, like cooking and so on, while reciting mantras That could  be quite annoying to people around you.  However, if you understand spiritual practice in its true sense, then you can use all twenty-four hour of your day for your practice. True spirituality is a mental attitude that you can practice at any time.  For example, if you find yourself in a situation in which you might be tempted to insult someone, then you immediately take precautions and restrain yourself from doing that.  Similarly, if you encounter a situation in which you may lose your temper, immediately you are mindful and say, No , this is not the appropriate way.  That actually is a spiritual practice.  Seen in that light, you will always have time."
