The heart of Dharma practice is meditation. The purpose of meditation is to pacify and calm the mind. When our mind is peaceful we have concerns and problems, and experience true happiness. But if we lack peace of mind, no matter how pleasant that the external conditions around us, we can not be happy. If we practice meditation, we will discover within ourselves increasingly peace, serenity and pure happiness. Finally, we will enjoy every moment of happiness, even if we have to deal with adverse circumstances.
Usually we find it difficult to control our mind. It is unstable and vulnerable to external circumstances, such as a balloon at the mercy of the whims of the wind. If we get our mind is happy, but otherwise we get angry. For example, if we acquire an object we wanted or struck up a new friendship, we rejoice too much and cling to them with intensity, but as it is not possible to fulfill all our desires and it is inevitable that some day we shall separate us from our possessions and friends this attachment only to cause us pain. When not what we want or we lose something that we like, we become despondent or irritated. When we have to work with a person that we find unpleasant, we get cranky and we take offense at every opportunity; as a result, we cease to be effective in our work and find satisfaction in it, and suffer stress.
We suffer these changes in our mood because we are too closely involved in the external situation. We are like children who are excited to build a sandcastle on the beach, but they get to mourn when the waves destroyed. Through meditation, we learn to create a space within ourselves and flexibility and clarity that enables us to control our minds without affecting us the constant changes in external circumstances. Gradually, we acquired a mental stability that allows us to be always happy, rather than oscillate between extremes of euphoria and despair.
If we practice meditation regularly, finally able to eradicate mental disorders, the cause of all our problems and suffering. Thus, we experience permanent inner peace, which is known as liberation or nirvana in Sanskrit. Since then, day and night, life after life, experience only peace and happiness.
