Liberation is a permanent inner peace attained through the complete abandonment of delusions.
We should remember that every opportunity to develop anger is also an opportunity to develop patience.
Normally we seek happiness outside ourself. We try to obtain better material conditions, a better job, higher social status, and so on; but no matter how successful we are in improving our external situation, we still experience many problems and much dissatisfaction. We never experience pure, lasting happiness. In his Dharma teachings, Buddha advises us not to seek happiness outside ourself but to establish it within our mind. Introduction to Buddhism
Everyone wants to be happy and no one wants to suffer, but very few people understand the real causes of happiness and suffering.
Our problems do not exist outside our mind. The real nature of our problems is our unpleasant feelings, which are part of our mind.
When things go wrong in our life and we encounter difficult situations, we tend to regard the situation itself as our problem, but in reality whatever problems we experience come from the side of the mind. If we were to respond to difficult situations with a positive or peaceful mind they would not be problems for us; indeed, we may even come to regard them as challenges or opportunities for growth and development. Problems arise only if we respond to difficulties with a negative state of mind. Therefore, if we want to be free from problems, we must transform our mind. Modern Buddhism
