2. THE SECOND NOBLE TRUTH: The origin of suffering is attachment.
The origin of suffering is attachment to transient things and the ignorance thereof. Transient things do not only include the physical objects that surround us, but also ideas and, in a greater sense, all objects of our perception. Ignorance is the lack of understanding of how our mind is attached to impermanent things. The reasons for suffering are craving and ignorance. Because the objects of our attachment are transient, their loss is inevitable, thus suffering will necessarily follow.
People who desire to own many things also can never be fully satisfied too. They soon become dissatisfied with what they already have and desire more. When we have obtained something we desire, we may want more and more of it, and so greed arises. Because of desire and greed, people will lie, cheat and steal to get what they want. Uncontrolled desires can also lead to addiction, for example, to smoking, drinking and overeating, all of which lead to suffering and cause mental and physical harm.
If another person prevents one from getting what is desired, one may feel anger towards that person. Desire, when obstructed, can lead to ill will and anger. This in turn can lead to harsh words, violent quarrels and even fights or killings. All this is suffering.
Ignorance is the inability to see the truth about things, to see things as they really are. There are many truths about the world which people are ignorant of because of the limitations of their understanding.
When people develop their minds and acquire wisdom through study, careful thought and meditation, they will see the Truth. They will see things as they really are. They will understand the suffering and impermanence of life, the Law of Cause and Effect and the Four Noble Truths. By overcoming craving and ignorance, they will attain happiness and Enlightenment just as the Buddha did about 2500 years ago.
