Buddha attained supreme enlightenment through meditation and then spent His whole life converting sentient beings. The Four Foundations of Mindfulness Sutra teaches a method of meditation to gain no-self, and to enter Nirvana.
Karma
Karma is one of the fundamental doctrines of Buddhism. Everything that we encounter in this life, good or bad, sweet or bitter, is a result of what we did in the past or from what we have done recently in this life. Good karma produces happiness; bad karma produces pain and suffering.

So, what is karma?
Karma is a Sanskrit word, literally means a deed or an action and a reaction, the continuing process of cause and effect. Moral or any good or bad action (however, the word ‘karma’ is usually used in the sense of evil bent or mind resulting from past wrongful actions) taken while living which causes corresponding future retribution, either good or evil transmigration (action and reaction, the continuing process of cause and effect)
Our present life is formed and created through our actions and thoughts in our previous lives. Our present life and circumstances are the product of our past thoughts and actions, and in the same way our deeds in this life will fashion our future mode of existence. A karma can by created by body, speech, or mind.
There are good karma, evil karma, and indifferent karma. All kinds of karma are accumulated by the Alayavijnana and Manas. Karma can be cultivated through religious practice (good), and uncultivated.
For sentient being has lived through innumerable reincarnations, each has boundless karma. Whatever kind of karma is, a result would be followed accordingly, sooner or later. No one can escape the result of his own karma.
