Teachings of Lord Buddha

Some scholars believe that some portions of the Pali Canon and the Agamas could contain the actual substance of the historical teachings (and possibly even the words) of the Buddha.This is not the case for the later Mahayana sutras.The scriptural works of Early Buddhism precede the Mahayana works chronologically, and are treated by many Western scholars as the main credible source for information regarding the actual historical teachings of Gautama Buddha.

Some of the fundamentals of the teachings of Gautama Buddha are:

• The Four Noble Truths: that suffering is an inherent part of existence; that the origin of suffering is ignorance and the main symptoms of that ignorance are attachment and craving; that attachment and craving can be ceased; and that following the Noble Eightfold Path will lead to the cessation of attachment and craving and therefore suffering.
  
• The Noble Eightfold Path: right understanding, right thought, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration.
  
• Dependent origination: that any phenomenon 'exists' only because of the ‘existence’ of other phenomena in a complex web of cause and effect covering time past, present and future. Because all things are thus conditioned and transient (anicca), they have no real independent identity (anatta).
  
• Rejection of the infallibility of accepted scripture: Teachings should not be accepted unless they are borne out by our experience and are praised by the wise. See the Kalama Sutta for details.
  
• Anicca (Sanskrit: anitya): That all things are impermanent.
  
• Anatta (Sanskrit: anātman): That the perception of a constant "self" is an illusion.
  
• Dukkha (Sanskrit: duḥkha): That all beings suffer from all situations due to unclear mind.

However, in some Mahayana schools, these points have come to be regarded as more or less subsidiary. There is some disagreement amongst various schools of Buddhism over more esoteric aspects of Buddha's teachings, and also over some of the disciplinary rules for monks.
According to tradition, the Buddha emphasized ethics and correct understanding. He questioned the average person's notions of divinity and salvation. He stated that there is no intermediary between mankind and the divine; distant gods are subjected to karma themselves in decaying heavens; and the Buddha is solely a guide and teacher for the sentient beings who must tread the path of Nirvāṇa (Pāli: Nibbāna) themselves to attain the spiritual awakening called bodhi and see truth and reality as it is. The Buddhist system of insight and meditation practice is not believed to have been revealed divinely, but by the understanding of the true nature of the mind, which must be discovered by personally treading a spiritual path guided by the Buddha's teachings.

Physical characteristics of Lord Buddha

Buddha is perhaps one of the few sages for whom we have mention of his rather impressive physical characteristics. A kshatriya by birth, he had military training in his upbringing, and by Shakyan tradition was required to pass tests to demonstrate his worthiness as a warrior in order to marry. He had a strong enough body to be noticed by one of the kings and was asked to join his army as a general. He is also believed by Buddhists to have "the 32 Signs of the Great Man".
The Brahmin Sonadanda described him as "handsome, good-looking, and pleasing to the eye, with a most beautiful complexion. He has a godlike form and countenance, he is by no means unattractive."
"It is wonderful, truly marvellous, how serene is the good Gotama's appearance, how clear and radiant his complexion, just as the golden jujube in autumn is clear and radiant, just as a palm-tree fruit just loosened from the stalk is clear and radiant, just as an adornment of red gold wrought in a crucible by a skilled goldsmith, deftly beaten and laid on a yellow-cloth shines, blazes and glitters, even so, the good Gotama's senses are calmed, his complexion is clear and radiant."
A disciple named Vakkali, who later became an Arahant, was so obsessed by Buddha's physical presence that Buddha had to tell him to stop and reminded Vakkali to know Buddha through the Dhamma and not physical appearances.
Although the Buddha was not represented in human form until around the 1st century CE (see Buddhist art), the physical characteristics of fully-enlightened Buddhas are described by the Buddha in the Digha Nikaya's Lakkhaṇa Sutta.In addition, the Buddha's physical appearance is described by Yasodhara to their son Rahula upon the Buddha's first post-Enlightenment return to his former princely palace in the non-canonical Pali devotional hymn, Narasīha Gāthā ("The Lion of Men").

Death / Mahaparinirvana of Lord Buddha

According to the Mahaparinibbana Sutta of the Pali canon, at the age of 80, the Buddha announced that he would soon reach Parinirvana or the final deathless state abandoning the earthly body. After this, the Buddha ate his last meal, which he had received as an offering from a blacksmith named Cunda. Falling violently ill, Buddha instructed his attendant Ānanda to convince Cunda that the meal eaten at his place had nothing to do with his passing and that his meal would be a source of the greatest merit as it provided the last meal for a Buddha. Mettanando and von Hinüber argue that the Buddha died of mesenteric infarction, a symptom of old age, rather than food poisoning.The precise contents of the Buddha's final meal are not clear, due to variant scriptural traditions and ambiguity over the translation of certain significant terms; the Theravada tradition generally believes that the Buddha was offered some kind of pork, while the Mahayana tradition believes that the Buddha consumed some sort of truffle or other mushroom.
The Mahayana Vimalakirti Sutra claims, in Chapter 3, that the Buddha doesn't really become ill or old but purposely presents such an appearance only to teach those born into samsara about the impermanence and pain of defiled worlds and to encourage them to strive for Nirvana.
"Reverend Ánanda, the Tathágatas have the body of the Dharma—not a body that is sustained by material food. The Tathágatas have a transcendental body that has transcended all mundane qualities. There is no injury to the body of a Tathágata, as it is rid of all defilements. The body of a Tathágata is uncompounded and free of all formative activity. Reverend Ánanda, to believe there can be illness in such a body is irrational and unseemly!' Nevertheless, since the Buddha has appeared during the time of the five corruptions, he disciplines living beings by acting lowly and humble."
Ananda protested Buddha's decision to enter Parinirvana in the abandoned jungles of Kuśināra (present-day Kushinagar, India) of the Malla kingdom. Buddha, however, reminded Ananda how Kushinara was a land once ruled by a righteous wheel-turning king that resounded with joy:
44. Kusavati, Ananda, resounded unceasingly day and night with ten sounds—the trumpeting of elephants, the neighing of horses, the rattling of chariots, the beating of drums and tabours, music and song, cheers, the clapping of hands, and cries of "Eat, drink, and be merry!"

Buddha then asked all the attendant Bhikshus to clarify any doubts or questions they had. They had none. He then finally entered Parinirvana. The Buddha's final words were, "All composite things pass away. Strive for your own liberation with diligence." The Buddha's body was cremated and the relics were placed in monuments or stupas, some of which are believed to have survived until the present. For example, The Temple of the Tooth or "Dalada Maligawa" in Sri Lanka is the place where the relic of the right tooth of Buddha is kept at present.
According to the Pāli historical chronicles of Sri Lanka, the Dīpavaṃsa and Mahāvaṃsa, the coronation of Aśoka (Pāli: Asoka) is 218 years after the death of Buddha. According to one Mahayana record in Chinese (十八部論 and 部執異論), the coronation of Aśoka is 116 years after the death of Buddha. Therefore, the time of Buddha's passing is either 486 BCE according to Theravāda record or 383 BCE according to Mahayana record. However, the actual date traditionally accepted as the date of the Buddha's death in Theravāda countries is 544 or 543 BCE, because the reign of Aśoka was traditionally reckoned to be about 60 years earlier than current estimates.
At his death, the Buddha told his disciples to follow no leader, but to follow his teachings (dharma). However, at the First Buddhist Council, Mahakasyapa was held by the sangha as their leader, with the two chief disciples Mahamoggallana and Sariputta having died before the Buddha.
