The Four Noble TruthsThe four visions that Siddhartha was hidden from all his life are what drove him to find the Four Noble Truths. When Siddhartha set out to explore the outside world, he saw old age, illness, death and the wandering monk. Siddhartha's ultimate goal was to end all the suffering he had experienced as well as that he had seen others experience. His discovery of the solution began with the recognition that life is suffering. The First Noble Truth is that the suffering of birth, old age, illness and death is inevitable – this suffering or unhappiness is also known as dukkha. This general suffering is everywhere, and it can be physical or mental. Physical pain can be seen and felt by anyone, as simple as aches and pains, delicate skin. For example, as we age, we have more difficulty seeing and performing daily activities. Even in the miracle of birth, the mother experiences incredible pain, even though she knows she must endure it. Additionally, even the happiest, most carefree people will eventually experience some form of suffering. The Buddha taught people to recognize that suffering is a part of life and cannot be avoided. However, this suffering does not only come from the body, it also comes from within. Those who suffer from loneliness, depression, anxiety, or who cannot satisfy their needs and desires suffer. Despite the negative aspects of suffering, Siddhartha also spoke of happiness through friendships, family life or health. However, the problem is that happiness is fleeting – or annica – and will not end all suffering. Buddhists believe that to end suffering, one must first accept the fact that suffering is a reality of life. The next aspect to recognize is what is causing such suffering? By observing people, Siddhartha discovered that suffering is caused by selfish desires and urges – aka tanha – as well as ignorance. Envy can be explained by the strong desire people have to please their senses. The truth is that none of the things we crave last very long, and in fact, say it's your favorite food, once finished it's forgotten as if it never happened – then you crave something else. People constantly crave, but ultimately they will never be fully satisfied; this is the reason why people repeat acts such as eating delicious food or having sex several times.
