The core of Buddha's Teaching is 'Dukkha' or suffering - the Four Noble Truths.To be free from suffering 'permanently' we need to live a moral life; we need to meditate - to look inward to realise the true nature of things; we need to cultivate the Noble Path. To support His Teaching on suffering, He expounded His theory of Impermance and Non-Self. Because all conditioned things are impermenance there is no 'permanent' happiness; Because our Body is just a hotel for our Mind to stay for this life time, ther is no Self Entity - this Mind entity migrate again and again for a billion time housed with a billion Bodys as long as we are in Samsara. To be out of Samsara and return to the True Mind, Buddha Nature, Emptiness we have to perfect the Eight Noble Path. Buddhism is 'Nowness'; Buddhism is Mind culture; Buddhism is looking inward to realise the nature of things; Buddhism is to evolve to higher consciouness; Buddhism is to be the Moon and not the reflection of the Moon.
Buddhism grew from the teachings of Siddhartha Gautam, the Buddha (hence BUDDHism). Some of his main teachings were karma, the Four Noble Truths and the Eightfold Paths.
Buddhism
Siddhartha Gautama is the Buddha and the founder of the teachings that comprise Buddhism.
The religious symbol for Buddhism is the teachings of the Buddha or the Three Noble Jewels.
Buddhism is a variety of beliefs and practices based on the teachings of Siddhartha Gautama
I am assuming that what you are asking is how does Buddhism today compare to what the Buddha taught. Buddhism over the years has been enriched by each culture that has been exposed to; changing the nature of practice just slightly each time. So Chan Buddhism (China) is slightly different in practice then is Zen Buddhism (Japan, Korea). But the teachings have always remained the same. Now when I speak of practice, it is the methods used to teach the Dharma (the teachings). The biggest change in Buddhism since the Buddha is the development of Mahayana Buddhism. Mahayana Buddhism, to which is the tradition I practice, added teachings from later Buddhas and Bodhisattvas to The Buddha's original teachings in regards to living a compassionate life to help all other beings. So Buddhism adapts the methods but never the message or teachings.
There are really only 2 distinct types of Buddhism, though there are subgroups to them. The two major groups are Theravada and Mahayana. Theravada is call the "teachings of the Elders" and is most closest to the original teachings of the Buddha. Mahayana incorporates teachings of later Buddhas and Bodisatvas into the Buddhas original teachings. All the differnt lineages of Buddhism fall within one of these two groups but all teachings agree as to what the Buddha taught and to what the objective of Buddhism is.
