Change only takes place through action, not through meditation and prayer.
It is necessary to help others, not only in our prayers, but in our daily lives. If we find we cannot help others, the least we can do is to desist from harming them.
Prayer alone will not make a happy life. A happy life must be built. You must act.
Whether we consider the individual, family, local, national or international level, peace must arise from inner peace. For example, making prayers for peace while continuing to harbor anger is futile. Training the mind and overcoming your anger is much more effective than mere prayer. Anger, hatred and jealousy never solve problems, only affection, concern and respect can do that.
It's unrealistic to think that the future of humanity can be achieved only on the basis of prayer; what we need is to take action.
Peace does not come through prayer, we human beings must create peace.
To foster inner awareness, introspection, and reasoning is more efficient than meditation and prayer.
