In all meditations and The Four Foundations of Mindfulness, The Breath Meditation is the superiority over the dhamma. It is a sudden Enlightened  Zen by contemplating directly the human heart with a clear awareness and without open hole that enters the spread of false  thoughts. The breath is the liasion base  from the  Manas (Afflicted Consciousness) and Alaya (Foundation Consciousness)  to continue the life impacting into the cause and effect of birth and death of the beings. Therefore, correct breath can not only make the body and mind stable but release from the erroneous consciousness with chaining  Samsara, the cycle of births and deaths (birth, death, and rebirth: reincarnation) by the karma. What is the karma?

I. Karma (skt)-Kamma (p)
a). The meanings of 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 inumerable 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.
b). Karmas and Recompenses:
As mentioned above, karma is a product of body, speech and mind; while recompense is a product or result of karma. Karma is like a seed sown, and recompense is like a tree grown with fruits. When the body does good things, the mouth speaks good words, the mind thinks of good ideas, then the karma is a good seed. In the contrary, the karma is an evil seed. Thus the Buddha taught: “To lead a good life, you Buddhists should make every effort to control the activities of your body, speech, and mind. Do not let these activities hurt you and others.” Recompense corresponds Karma without any exception. Naturally, good seed will produce a healthy tree and delicious fruits, while bad seed gives worse tree and fruits. Therefore, unless we clearly understand and diligently cultivate the laws of cause and effect, or karma and result, we cannot control our lives and experience a life the way we wish to. According to the Buddha-Dharma, no gods, nor heavenly deities, nor demons can assert their powers on us, we are totally free to build our lives the way we wish. If we accumulate good karma, the result will surely be happy and joyous. No demons can harm us. In the contrary, if we create evil karma, no matter how much and earnestly we pray for help, the result will surely be bitter and painful, no gods can save us.
c). How does karma enter the Alaya-vijnana?:
When we act, either good or bad, we see our own actions, like an outsider who witnesses. The pictures of these actions will automatically imprint in our Alaya-vijnana (subconscious mind); the seed of these actions are sown there, and await for enough c
