What key things did Buddha say in his Deer Park Sermon?

After he attained enlightenment, the Buddha traveled to Deer Park in Sarnath in search of his former companions. This took five weeks.





When he found his five friends, he told them what he had discovered through his practice and enlightenment. These teachings are now called the Dhammacakkappavattana Sutra -- the Buddha's first teaching of the dharma.





The sutra sets out the fundamental teachings of what we now call Buddhism:





1. The Middle Way, between asceticism and indulgence


2. The Four Noble Truths


3. The Eightfold Path

The deer park teachings were on the four noble truths :


suffering


Certain major Mahayana sutras, including the Mahaparinirvana Sutra and the Angulimaliya Sutra, present variant versions of the Four Noble Truths of the Buddha:





the Truth of Suffering relates to the failure to recognize the eternity of the Buddha;


the Truth of the Cause of Suffering concerns the perversion and distortion of the True Dharma (i.e. wrongly insisting that the Buddha and Dharma are impermanent);


the Truth of the Cessation of Suffering relates to the correct meditative cultivation of the tathagatagarbha (indwelling Buddha Nature in all beings) and not erroneously viewing it as non-Self and empty; cessation of suffering also arises with the elimination of inner defilements, when one can then enter into the Buddhic Essence within oneself: ';When the afflictions have been eradicated, then one will perceive entry into the tath膩gata-garbha';;


the Truth of the Path to the Cessation of Suffering entails envisioning the Buddha, Dharma and Sangha as eternal, unshakable and indestructible. (Mahayana Mahaparinirvana Sutra)





The Pali Text reads like this :


The Nature of Suffering (Dukkha):


';Now this ... is the noble truth of suffering: birth is suffering, aging is suffering, illness is suffering, death is suffering; sorrow, lamentation, pain, grief and despair are suffering; union with what is displeasing is suffering; separation from what is pleasing is suffering; not to get what one wants is suffering; in brief, the five aggregates subject to clinging are suffering.';





Suffering's Origin (Samudaya):


';Now this ... is the noble truth of the origin of suffering: it is this craving which leads to renewed existence, accompanied by delight and lust, seeking delight here and there, that is, craving for sensual pleasures, craving for existence, craving for extermination.';





Suffering's Cessation (Nirodha):


';Now this ... is the noble truth of the cessation of suffering: it is the remainderless fading away and cessation of that same craving, the giving up and relinquishing of it, freedom from it, nonreliance on it.';





The Way (M膩rga) Leading to the Cessation of Suffering:


';Now this ... is the noble truth of the way leading to the cessation of suffering: it is the Noble Eightfold Path; that is, right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, right concentration.';
