If we train in meditation systematically, eventually we will be able to eradicate from our mind the delusions that are the causes of all our problems and suffering. In this way, we will come to experience the supreme permanent inner peace of nirvana. Then, day and night, in life after life, we will experience only peace and happiness. At the beginning, even if our meditation does not seem to be going well, we should remember that simply by applying effort to training in meditation, we are creating the mental karma to experience inner peace in the future. The happiness of this life and of our future lives depends upon the experience of inner peace, which in turn depends upon the mental action of meditation. Since inner peace is the source of all happiness, we can see how important meditation is.
